FeedHow to Fix Outlook 2007 Cannot Send Email Problem with Windows Vista & Linksys Router
By Ian Lee on Jun 8, 2007 in Hardware, Software, Technology
There have been quite a few complaints that Outlook 2007 (running in Windows Vista) is not sending out emails properly when paired with certain Linksys routers. I actually experienced this recently - what a mess. Thought I would share a quick fix and save some of you from hours of hair pulling.
For one reason or another, my Linksys WRT54GL wireless-G router began intermittently dropping DNS connections (4.2.2.2) even though the default gateway (192.168.1.1) respond normally to pings. In short, I can see and access other computers in the local area network, but there is no internet connection. After 2 weeks of tech support calls and more than 4 hours of total support time, the effort finally paid off. Linksys is sending a replacement unit.
During each call, tech support suggested changing MTU settings, disabling Block Anonymous Internet Requests, hard resetting the router, re-flashing the firmware, power cycling the modem & router, running static IP & DNS settings on each computer, adjusting various wireless settings, etc…. You name it, we tried it. Of course, after each tedious call, the router would work fine. After some usage, the DNS drop would return. It got to the point that every 24 hours, the router needed a hard reset and a full re-setup to work properly again.
The WRT54GL has a 3 year warranty so I chose the cross shipment method for replacement. Cross shipment is where Linksys sends you a replacement unit first. After you receive the replacement, you simply send back the defective unit as opposed to having to send in your unit first before Linksys sends you another. The only difference is when you choose the cross shipment method, Linksys will put a hold on your credit card for the retail amount of the unit that they have sent you. Once they receive the defective unit, the credit card hold will be cancelled. Fair enough. I went through the RMA process and am awaiting a replacement unit.
After dusting off and setting up my old Linksys wireless-B BEFW11S4 router, all was well again… except for Outlook not being able to send out any emails! After some quick research, it turns out that the BEFW11S4 has been well documented to have email send issues. Two must do’s for this router to unblock Outlook sending emails are:
-
1. Set Max MTU to 1492 (rather than the disabled default of 1500)
- TriggerPort Range: 25 ~ 25
- IncomingPort Range: 113 ~ 113
2. Port triggering should be setup with these settings:
After these settings, both Outlook 2003 (running under Windows XP) & Outlook 2007 (running under Windows Vista) were still not able to send emails out. I had to further tweak each computer manually to send out emails via Outlook. Here is what I had to do in the time being until the new replacement router arrives.
Under each Outlook email account, I removed my normal SMTP setting of smtp.domain.com (your SMTP will be different and is based on your own domain name). It was replaced with an SMTP setting from my ISP - in this case, my cable provider. This solved the XP system but not the Vista system. For Outlook 2007 under Windows Vista, when using your ISP’s SMTP, an additional step of disabling authentication is required.
Under Tools >> Account Settings >> Account (Double clicking on each email account) >> More Settings >> Outgoing Server Tab, uncheck “My outgoing server (SMTP) requires authentication” like so:
Voila! Emails are going out again.
Funny enough, after switching SMTP settings, I disabled the above Max MTU settings and Port Triggering on the BEFW11S4 router and emails are still going out. Go figure!
Not sure why there are so many issues (& resolutions) in the Linksys forums regarding email send issues with certain Linksys routers but there you go. Hope this quick fix can help others with your Outlook email send problems.
In the meantime, I hope Purolator gets here quick with that replacement unit! I miss my faster wireless transfer speeds and stronger WPA encryption!

You are welcome Paula. Glad the article helped. Enjoy sending all those emails again!

Thank you!!! I second Paula’s comment. I got this new fancy XPS M2010 with Vista and just could get email to sent for the past few weeks. Compared everything line by line with my old machine and almost pulled my hairs out
Glad I was able to google your tips.

We are having the problem with Outlook 2007 and turning off the authentification works for a while, but then later needs to be turned on, then later needs to be turned off again.
No clue yet, our ISP who we use for outgoing mail does not see a problem because they only see the traffic that goes. I believe it is something in Outlook 2007, not at the ISP. If anyone has more information, please post.

Also having the problem but with Outlook 2003 and turning off the authentification works for a while. 2 new noteboooks running fine on Vista and Outlook 2003. Only that 3 original pc cannot send out msg in outlook. Tried everything. Agree with Don Williams that its Outlook’s problem and not OS, Router or ISP or anything else. Will fiddle around the outward mail server port in outlook 2morow. Will update if it works.

Ian, I still am unable to send emails after making your suggested tweeks for Outlook 2007 (Vista) using a Linksys router. Any other suggestions? I’m losing my mind!!!!
By Ian Lee on Jul 11, 2007 | Reply
@Meg: Many ISP’s are beginning to block port 25, the default smtp and this may be your issue as well. If you can provide the following info, hopefully we can help you troubleshoot the no-send issue.
Operating System: Vista
Email Client: Outlook 2007
Linksys Router (model):
Email Address (everything after the @ sign):
SMTP Setting:
SMTP Port (See Advanced tab from above image):
ISP (the provider that you use to surf the internet):
Let’s start from there.

Similar problems to Don, NOS and Meg. E-mail works one day and not the next. Brand new Dell E1705 with Vista, Outlook 2007, linksys befw11s4 v.2, @verizon.net, has been working with the box checked for outgoing requiring authentication,SMTP port = 25, Verizon is ISP.

Eric, what is your SMTP setting & who is your ISP?
Operating System: Vista
Email Client: Outlook 2007
Linksys Router (model): befw11s4 v.2
Email Address (everything after the @ sign): @verizon.net
SMTP Setting:
SMTP Port (See Advanced tab from above image): 25

Ian,
SMTP setting: Use same setting as incoming server
Verizon DSL is my internet provider, my web browser is MS explorer.
BTW - I can’t send or receive e-mails when my email issues pop-up.
By Eric on Jul 14, 2007 | Reply
Sorry for being clueless - outgoing.verizon.net is probably what you are asking for as my SMTP setting
By Ian Lee on Jul 14, 2007 | Reply
Hey Eric,
It sure is odd that both receive and send breaks. This tells me that either or both SMTP and POP settings are off. Your SMTP should not be the same as your POP setting. At least not per Verizon’s instructions.
Try the above settings and see if you can at least receive email. That would be step 1.
I have had my own intermittent send issues with the BEFW11S4. This particular router has been well documented in the Linksys forum to have major issues with sending emails in various setups.
Have you tried Verizon tech support? They should be able to help since you are accessing their emails.
If you have tried the above settings (including the Max MTU & port triggering), I would recommend a different router. In my opinion, I think the BEFW11S4, although it works, is out dated and does not work well with more recent setups.
If you find a solution do post back. The only way I was able to resolve intermittent issues on the BEFW11S4 was to switch back to a newer WRT54GL.
Hope that helps.
Addon: Forgot to mention that you can try by-passing the BEFW11S4 temporarily by plugging your computer directly into the modem. If sending and receiving email works this way, then you know the router is the culprit.

I have found an issue with server address’s, both my incoming an outgoing mail servers are the same address and every now and again it stops sending mails and just keeps asking for login details for the outgoing mail server. I found whenever this happens if i check the account setup it has changed the outgoing mail server to localhost. Change it back to the SMTP server address and it works again.
Looks like a bug in Outlook to me, very annoying.

Hi -
I’ve got a “can’t send email from Outlook/Vista with a Linksys router” problem
Operating System: Vista
Email Client: Outlook 2002
Linksys Router (model): WRT350N-SG Wireless-N Gigabit Router with Storage Link
Email Address (everything after the @ sign): @att.net
SMTP Setting: imailhost.worldnet.att.net
SMTP Port: 465 (att uses SMTP:465 and POP3:995
ISP austin.rr.com
I can receive mail on this Vista PC (and all other PCs (non-Vista) can send/receive). I cannot SEND mail on this Vista machine.
In Outlook under “Test Account Settings” - all Succeed except last step which fails stating “Unable to send test Message. Please verify E-mail Address field.”….Ok, I re-entered/confirmed correct address, tried other accounts and deleted the outlook account to try and fix, to no avail.
I tried 1492 and 1450 MTUs and have tried port trigger ranges inclusive of above SMTP/POP3 for att.net === Seems like my email account name is getting truncated?
Spoke with Linksys and att.net - both collude to blame Microsoft ;-)…please help me.
Ted
By Ian Lee on Aug 3, 2007 | Reply
Ted, since your email is at att.net and your ISP is at rr.com, you could be affected by RR blocking port 25.
Have you tried accessing the affected account on your non-Vista machines? Does this work?
I would also try plugging your problematic Vista machine directly into the modem (by-passing the router) to see if the router is the cause.
Hope that helps.
By Ted on Aug 3, 2007 | Reply
Ian, thank you for your comments. att.net uses 465, not 25 (25 doesn’t work with att.net if you’re accessing them via another ISP). 465 works on other machines (non-Vista PCs). So RR blocking 25 isn’t problem. I don’t have another router to access my RR connection and so can’t bypass it either (it’s a cable BB connection). ?
By Ted on Aug 3, 2007 | Reply
Ian, sorry, your other question, yes the account works if I go to it either as web mail access or via an Outlook Client on and XP machine (on the same network). Ted
By Ian Lee on Aug 3, 2007 | Reply
Ted, glad to know you have the port issues sorted. This sure sounds like Vista is the culprit.
From your Vista machine, instead of plugging the network cable into your router, can you plug it directly into your cable modem? You will have to unplug your router from your modem before doing do. Then reboot and try again.
Not sure if your hardware will allow you to do this but if you can, it will at least remove Linksys from the equation (or some combination of Vista + Linksys).

I’ve been having intermittant problems with e-mail getting stuck in Outbox. Just read a response in MS forum TechNet where someone said hand type in e-mail address. Tried it and it worked. Seems some e-mail addresses when inserted from Contacts puts parantheses around e-mail addresses. These will be the “intermittant” ones stuck in Outbox. Hope this helps someone.

I am not able to send any emails. I am not able to send any emails using outlook express or yahoo. It gives me an error message.

I am using Outlook 2007 on Windows Vista Business and cannot send mail. I am also using Windows Mail (OE with a new name) and having absolutely no problem sending mail with that on multiple accounts. These OE accounts that work fine are on my domains hosted by the same ISP as my Outlook 2007 email, which does not work.
I am connected at home via Netgear Wireless router to my Verizon DSL service. I have tried many, many things (smtp auth on/off, port 25 changes, etc) but nothing has resolved the issue… until now.
I tried Lou’s solution above and it worked. Bam! Messages are gone. Note that all of my contacts were loaded in using a PDA running PocketPC and using Microsoft Hotsync. Any contacts that I had manually loaded in were working fine. I just never made the connection that the imported contacts could be the problem.
I opened the imported contact for an email that was stuck in the outbox, re-keyed the email field and saved the contact, re-addressed the message to the same guy and it sent immediately.
Might be a fix for some of you, especially if you imported contacts to Outlook 2007.
Cheers!

The root problem is that ISP’s (such as BT, wanadoo/orange …) only allow sending email via their SMTP server. The default port for SMTP is 25 (i think). They block this port and force it to go via their server only. Therefore you need to switch your outgoing smtp server to be the one the your ISP provides.
Alternatively you may have an alternative SMTP server as long as its not on port 25.
They do this to stop spam senders.
By Bruce Sellnow on Sep 11, 2007 | Reply
Update on my earlier post. I have tried a simpler approach. Any messages that get stuck in my Outbox are always ones that are addressed to an Outlook contact. When a message gets stuck, I open the message, and double click the name in the TO: field to open the contact. I then just “SAVE & CLOSE” the contact without making any changes. I hit SEND on the message and it goes… Every Time.
Future messages to that contact are not held up, but get sent immediately. In my humble situation, this is definitely something to do with importing contacts.
(Do I get a free t-shirt or something for discovering this…?)

Hey - update on my earlier post on outbox messages stuck. I was using Office 2003 (and OE 2003), after many patches, and yes the earlier posts on fixing imported addresses from contacts worked, yet still have intermittent stuck msg complaints from a persistent and tireless user community (my wife). “My” solution to all issues was to break down and buy Outlook 2007 (only) for $109. Installed fine, everything works perfectly now (relative term for MS). Not sure that all noted that my original query was about OE 2003, not OE 2007. Thanks for the help along the way. This is what I get for trying to run XP Office on Vista OS.

ok so i am not a computer person and i’ve tried to fix this problem myself but it obviously is not working. i have outlook 2007 with XP. I just upgraded to 2007 a few weeks ago and the email worked fine at first but then it stopped. i get error messages coming back undeliverable saying that my email was denied from that location or something along those lines. i don’t know how to fix this and am hoping that someone can give me easy to follow dummy proof instructions so i can fix this.
thanks

Hello,
Since I’ve had Vista, I have not been able to send email via Outlook 2007 or 2003, as well as Windows Mail. I do not have a router anymore. I certainly can receive mail but just cannot send it. I have comcast cable for my hi-speed internet service, and, thus, I set my SMTP to smtp.comcast.net and I keep the Authentication Required box unchecked.
Any clues??
Thanks, Diane

I have problem using outlook 2003 or Mozilla sending out emails on my wired or wireless computers. Receiving is perfectly fine at anytime. My setting is as follows:
Operating system: Window XP
Mail Client: Outlook 2003 or Mozilla
Router: Linksys WRT54GS Wireless G firmware V7
Email addreass: XXX@comcast.net
SMTP: smtp.comcast.net, port 25 or 587, secure and authentication used
If connected directly to cable modem, everything works fine. Just when plugged into the router, sending email is blocked with the error message “98.207.32.236 blocked by idap:ou=rbl,dc=net” in both Outlook and Mozilla, meaning Outlook is not the problem as Comcast blamed. Amazingly, when I tapped into my neighbor’s unsecured wireless network, with Linksys router and Comcast as ISP, I am able to send and receive emails. But when he taps into my network, sending email is not working either. Seems like router problem, but I suspect Comcast may have contributed to this problem. I have contacted Comcast, Linksys and HP help, they all said it is not their problem. Oh, I went out to buy another D-link router and new Linsys cable modem, and I encounter the same old frustration. Please help.

Vista + Outlook 2007 = doesn’t work sending emails. Went through the BS tech support changing ports to 995, 465, turning on SSL. Webmail works to two different POP3 accounts, but Outlook doesn’t. If I run Outlook 2007 as a normal user it fails. If I right click, run as Administrator, then I can Send emails. I don’t know what the difference is, or how to set it permanently. Thanks Microsoft.

Not all IT literate so pretty peed off…I have a new Dell computer (XPSM1330)and it came with vista and a MS Office disk. I tried to set up outlook this morning to accept a work email address with same incoming and outgoing IP address (numerical not in words). This was to work alongside my home mac which uses an orange livebox (the home account works fine) but neither the mac (using the switch identities mode)nor the PC can send emails from my work account. I can receive mails but cannot send them. The bizarre thing is that I took the laptop to a IT repair shop this afternoon and it worked whilst I was there (!) but they have a BT line. Orange technical support was pretty useless but surely its them at fault otherwise why did it briefly work? Any advice? (settings are at 110 and 25 - having read loads of postings on various sites) Thanks all

I was having similar problems with my Outlook 2007 and Vista. I am also running Trend Micro. I was unable to send any e-mails over 2mb. However I had a brain wave and decided to shut down Trend Micro, suddenly I could send 3mb files. In the settings of Trend micro I have since disabled “Check for threats in Outgoing Mail” under “Virus and Controll” settings and now everything is working fine!!
Also another point that might help for some people, disable all add-ins and see what happens.
I hope this helps people as this is a very frustrating problem and took me quite some time to figure it out!

ROUTING THROUGH ATT FROM THE INSIDE for email
As all those previous posters mentioned, i was unaware of this ATT change for SMTP delivery. as it apparently seems that i got this without warning when i started sending mail through my router and notice that even tho i could receive mail i couldn’t send it.. funny thing was as a tech I’ve always had 2 wireless transmission ports going to different providers and when i couldn’t send on one i would send on the other. that was until my router bridge died and had to switch over to the ATT circuitry.
Woah! no more mail send??? as I’ve had this happen on other connections (usually public) and since i program routers, this seemed hairy, when i stumbled on Google to find people blaming Linksys for a problem they didn’t have especially since thats code i work with.. further examination found, as all you have spoken about for the last several months, is that the no-email play contributed to the router blame when there weren’t any, and the most likely culprit is ATT.
I never had port 25 problems in the past: so it was good when I tried this solution as a workaround and it solved a temporary issue..
SOLUTION
first: if and when you change Outlook, mine was 2003, oh and I do have Windows, Mac and Ubuntu machines as i am totally agnostic to issues relating to bloat, crap, and humanware, the latter (stupid human policy implementations) relating to enterprise/politics/money and outsourced stupidity! (and these are all humanstupid) a machine doesn’t need a human to screw it up. (technoRANT closed)
you will change the ports for workarounds: the SMTP port mapping on the last page of Outlook’s “email account settings”: “more settings/advanced” page please set that to SSL first close and go back into setting, change the port to 465 as my pop3 did seem to work just fine! save and exit BUT BEWARE! FOR THIS TO WORK! WHEN YOU HIT THE SEND MAIL BUTTON YOU BE ASKED TO ACCEPT A KEY(CERTIFICATE) IF YOU DON’T, YOU WILL HAVE REAL PROBLEMS, AS THIS KEY ALLOWS YOU TO TRANSIT YOUR MAIL THROUGH TO YOUR OTHER MAIL EXCHANGERS YOU HAVE ACCOUNTS FOR VIA ATT ONLY! and for this workaround and I’m referring to you war drivers out there that roam the autoconnectable public domain of open access points with your laptops. since this is a setting most commonly relateable to ATT this effect will not sit well for most other providers and connections that don’t have this problem. that you may have to change back for.
solving the problem is definitely asking your ATT PROVIDER THROUGH THE FORM TO CHANGE THIS:
In any case, AT&T allows port 25 connections to its own mailservers, and they will remove the port 25 block on your service if you request it. You can actually do this *online* without having to spend time on the phone… go to the following link for more information, and see item #4 on that page:
http://help.sbcglobal.net/article.php?item=4640
You can have this lifted online at:
http://helpme.att.net/servabuse.php
Under “Abuse type” select “Opt Out port 25″
Under “Abuse Occurred In” select “email”
After 24 hours, power-cycle your modem to activate the change.
last few lines lifted from previous posts that really solved some issues, thanks to Amir and Peter for those little nuggets

I must congratulate and thank Bruce Sellnow (posts on Sep 1st and 11th)- he hit the nail on the head. Who would of thought that his simple fix would alleviate so much frustration. My own machine is running Vista Business and Outlook 2007 as was Bruces, and suffered the exact same fate. I confirm and reiterate, his solution is 100% successful for fixing the “outlook will not send” problem we were experiencing….and it is most assuredly an issue with importing contacts

Hello all - very relieved to say all working now and for users in UK the problem (despite them refuting this and a pretty ineffective but undoubtedly expensive call to their help desk) was Orange not allowing non Orange email addresses to send mail over their broadband connections. Have moved to BT and it now works fine. Hooray - so not a problem with Vista working in conjunction with Outlook in my case.. thanks all - have a great 2008

I just switched to a new computer with Vista and Outlook 2007. I could receive email through Outlook using my att.net account, but I could not send email. I would keep getting an error message about needing to verify my email address. I saw the postings about unchecking the box requiring authentication for the SMTP server in the Outgoing Server tab of the Email Settings and decided to try that. However, when I got to that screen, I saw that the authentication box was not checked. I decided to check the box and see what happened. Now I can send emails just fine! I realize that this is contrary to others’ experiences, but thought I should throw it out there in case anyone else is in my situation.

Hello:
I am in charge of about a dozen computers here. We just added three new ones with Vista Business and Office 2007. With one machine send and receive works but some emails don’t come in until the next day. Doesn’t seem to be a pattern of who sent it and whether there is an attachment or not. My second machine works fine. The third machine has a problem sending and receiving SOME emails. Some outgoing addresses bounce back and some just disappear. Some incoming messages come through and some disappear. We have a Linksys BEFSX41 router(no wireless). We also have Exchange. The IT staff for our server have spent hours to make sure there is no problem there. Thanks for any help you can give.

So I have 2 XP PCs Outlook 2003 SMTP= outgoing.verizon.net; 1 XP PC Outlook 2007 SMTP=smtpout.secureserver.net; 1 Vista PC Outlook 2007 SMTP=outpoing.secureserver.net. Now all is happy. go figure!!

Help!!
I just discovered that some of the emails that are showing in my “sent” folder for Outlook 2007 were not actually received… it looks like this happens when I have a link in the body, although not sure why as it appears to be a recent problem (or one I never realized). I have links in my signature so not sure why this matters, but it’s the only thing I can see so far. This appears to be true if I reply or forward an email that had a link in the original message.
any ideas?
Pete

Hi Pete,
I also have the same problem like you. The email that i sent is already in sent box, but people who suppose to receive my email is not receiving anything till now. I notice that this problem happening from certain date. Please help me….
Is this has something to do with virus, bug??
Thanks a lot for your help

I have found a workaround at http://blogs.technet.com/usefultechnology/archive/2006/01/30/418304.aspx (works for me). In short:
“Open the item that’s stuck in your Outbox, then (and this is the important bit) click on a different folder in the main Outlook window, now press Send and don’t go back into the Outbox folder until the mail has left.
“.
Good luck!

I have the same problem, however, I have two different routers, a Linksys WAG200g on ADSL and a SMC Barracade SMCWBR14-G on Satellite connection. The linksys fails, while the SMC passes and works..
At first I thought it was the ISP, but then when I switch back and forth I see its working.
my System is WinXP SP2, Office 2007.
I treid the MTU < 1500 & auto but did not work..
here is the Linksys workaround (it did not work)

I am having problems with an email that is blocking my sending other emails. I attempted to forward and email and it keeps coming up - ” Message could not be displayed
Windows Mail encountered an unexpected problem while displaying this message. Check your computer for low memory or low disk space and try again.” I cannot delete it due to another error message: “An unknown error has occurred”. Help! I purchased this computer last year with Vista on it and it has only given me problems ever since…

Very handy tip for Vista users and this has been a definate issue with email on vista! thanks

To disable the SSL Authentication is not a good Solution. Then you cancel your secure login. Try to use the cloce mac address feature on the linksys router. Some ISP require that, so you clone the mac of your PC to your Router. I had the same problem an than it works finde. Best regars from Hamburg in Germany…. Michael

I have a simular problem. windows vista with outlook 2007 and trend micro with a linksys router but not wireless. heres my deal. i setup 100s of computers with outlook 2003 with no issues. i get this vista machine with outlook 2007 and it sends and receives fine but when you add an attachment over 500kb it just sits in the outbox. i tried webmail and it sends fine so i know its something to do with outlook 2007 or trend micro. i disabled trendmicro in services and tried again and no luck. i thought it was business contact manager so i removed that. still no luck. it cant be an smtp setting because no mail would go out then. it has to be something to do with trendmicro or now Im reading maybe linksys.
any suggestions?

I cannot send email anymore. Up until last week, I could receive and send email fine. I can not attribute any installation or system change to causing this error to happen.
I am running the following:
Operating System: MS Vista Home Premium
Email Client: Outlook 2007 (12.0.6212.1000) SP1 MSO (12.0.6213.1000)
Linksys Router (model): WRT54G
Email Address @oh.rr.com
SMTP Setting: smtp.oh.rr.com
SMTP Port: 25
ISP : Road Runner – Time Warner Cable
***
I keep getting the dialog box that tells me to enter my network password. I do (and check to save it) and then it won’t down load or send my email!
Exasperation is an understatement as I don’t know what I am doing wrong and have spent over 25 hours reviewing help/MS KB articles/discussion groups/surfing the web for solutions and trying different things.
I have tried the following:
– I am able to view email on the road runner website, so I know that the
email/password is correct.
– http://www.msoutlook.info/question/40
– http://support.microsoft.com/default.aspx?scid=kb;en-us;290684
executed method 1 and method 2;method 3 said not to use if you were
running vista
– Removed all accounts on both the admin user and the standard user,
rebooted and added the account back to the standard user login again.
– Turned off inbound, outbound, IM scanning, Spam filtering in McAfee
– uninstalled McAfee
– installed Eset Nod32
– tried the port thing in the Linksys admin screens mentioned above.
– tried the checking/unchecking mentioned above.
– UnInstalled and re-installed Outlook 2007
– reset the Linksys settings to factory settings and reset up Linksys settings
– tested this email account and was able to receive email on an XP machine running Outlook on my network.
– downloaded and ran System Mechanic and resolved all identified errors.
– installed Zone Alarm
My email still doesn’t work.
Someone suggested that I uninstall and reinstall VISTA. I really don’t want to do this.
Does anyone have any suggestions?
Your help regarding this error would be MOST appreciated.
Thank you so much for your time.

Michael & Leila,
1. Have you tried by-passing the Linksys router and see if this works?
2.a. Or tried setting up your account on an XP machine but still have it go through the Linksys router and see if this works.
2.a. Use the XP machine from 2.a. and by-pass the router and see if this works.
With these steps, you might be 1 step closer in determining where the breakage happens. Not sure why Michael’s situation would break with 500+KB attachments. That is odd indeed.
So far you know:
Vista + Linksys = does not work
Now fill in:
Vista - Linksys =
XP + Linksys =
XP - Linksys =

Help!
I couldn’t send my emails from Outlook 2007 anymore. I m using OS-XP and Net gear router. As soon as I click the send button the email goes to out box folder and remains there for ever. But I m receiving some emails and that really worries me. Please help.

Another follow-up from my earlier post last September - I’ve been monitoring this thread ever since. On my laptop, I’ve connected to several different routers at family and friends’ homes, be it Linksys, Netgear, D-Link and a couple others. Every time I have a message stuck, I’ve noticed that it’s addressed to a person in my Outlook contacts that I haven’t used in a long time, specifically one that I haven’t SENT anything to from this laptop since upgrading to Outlook 2007.
FIX: Same process - open the email in the Outbox, double click on the recipient, which opens the contact card. Click Save and Close and then send the email… Still works every single time, regardless of the router. I just wanted to refresh this response to let you know it’s still a fix for me…
Sidebar: I really just need to go through all my contacts and open them and save them. I’m sure this would solve the problem. I wish I wasn’t so lazy…

thank you very much.. my windows mail is working again after unchecking the authentication thing…. after almost 7 weeks of trouble..you’re the only one who solved my problem. thanks again.

Ian,
Thanks for your suggestions.
Since I last posted on Mar 8, I was able to prove the following:
- Vista + direct connection to cable modem (without Linksys router) + Outlook 2007 = did NOT work
- XP + LinkSys + Outlook 2007 = works
- Vista + router at Panera coffee shop (couldn’t confirm router type – they didn’t know brand) + Outlook 2007 = did NOT work
So I went for drastic measures! I backed up my data files and re-installed Vista Home Premium.
I re-installed Outlook 2007 and moved my outlook data files in place.
Outlook 2007 set up wizard would NOT set-up/find my Time Warner Cable (ex-Comcast) settings. After setting up the email account manually (using the settings that I had used before, including unchecking the auth box) and email still not working and then talking with 2 incompetent TWC help desk reps who gave me 5 pieces of totally incorrect information (one told me that I shouldn’t put in the network password) , I finally was able to get my account set up correctly after talking with a competent TWC rep, who told me to uncheck “my outgoing server requires auth”,
Okay — are you sitting down?
I finally HAVE EMAIL AGAIN!!!!!!
I don’t know why the reset up of email didn’t work right away after the VISTA reinstall even though the settings that I manually set up were exactly the same as what I ended up with….
And more importantly, I have no idea what in VISTA got corrupted to make Outlook 2007 email all of the sudden stop working. I am estatic to report that VISTA + OUTLOOK 2007 + LINKSYS is living and playing well together. I am just hoping that one of the pieces parts doesn’t all of the sudden grab his bat and ball and head for home leaving the others in the lurch to play the game alone!

Re: Linksys: Outlook Express still will not send email even though the “Authentication…” box is unchecked.

I have a web hosting customer who reported the same problem trying to send mail out through my mailserver w/ Vista Home and Outlook 2007, and he said he googled and found a fix to be to disable “my outgoing server requires authentication,” yet I know my mailserver requires it. So it must be a bug in Outlook 2007 for Vista. He can send mail now. But if my mail servers were open I’d know about it.

Any suggestions???

Hi - I just had a similar problem with the same error message, but the solution was different. The problem was that I had copied and pasted a couple of numbers into my email. I didn’t realise it, but these numbers were in fact hyperlinked in the document from which I’d copied them. As soon as I deleted the hyperlinked version and just typed in the numbers, the email went. So just a thought - check whether anything in your email is an actual hyperlink to an external doc before you try to send it!
