Uncheck the Require logon …Authentication (SPA)

My outgoing server requires Authentication
– Use same settings as my incoming mail server

Incoming Server (POP3) : 995
– Check ==> This server requires ….
Outgoing Server (SMTP) : 587
– Auto

Leave a copy of message on the server

I had problems sending out emails (though I could receive them) from Outlook 2007 using my Cox account(which Cox says they don’t support), so I found the solution here:

I’m sure you get this all the time, but thank you all for the support. My problem has been resolved and it was due to using my ISP settings for the “outgoing” server. For the record, I have Vista, Outlook 2007, linksys router…..Thanks again

WoooHooo! After hours or mucking around, uninstalling and reinstalling, upgrading from Outlook 2003 to Outlook 2007, recreating profiles and lots of import/export, I have finally over come my problem where I was unable to send attachments. I thought it was Antivirus holding up the email, not allowing it to be sent, as a text only email would send OK but not if it had an attachement.

I am posting here to tell you all I have finally fixed my problem, and I hope it fixes yours too. First, heres what I did to no avail:
Delete and make new profile
Export everything and import into new profile
Run Norton Removal Tool (even though I have never had Norton)
Upgraded from Outlook 2003 to 2007
Delete contacts
Uninstalled Antivirus
Disabled Firewalls

and still could not send an email with an attachment. I found this site here: http://blogs.technet.com/fixit4me/archive/2009/01/14/disable-tcp-auto-tuning-fix-it-live.aspx which talks about running a Command in the CMD prompt

netsh interface tcp set global autotuninglevel=disabled

I did this (had to open CMD prompt as Administrator in Win 7) while my Outlook was closed. I then opened it back up, forwarded an email with an attachment and it sent no dramas!!!

THIS FIXED THE PROBLEM FOR ME!!! Before now I have seen the problem 3 times on XP, Vista and Win 7 machines, and previously I wiped them all because I couldn’t fix it. See how this goes and let me know!

Thanks for this article. I have sign only certificate but Outlook is not sending the signed e-mails using this certificate? Any solutions to this or this is not valid use case i.e. my certificate should be both sign and encrpt.

PROBLEMS:

- Hang opening e-mail with attachments > 100KB.
- Stuck in Outbox sending e-mails with attachments > 100KB. I get the following…

Error (0×800CCC13) : ‘Cannot connect to the network. Verify your network connection or modem.’

CONFIGURATION:

Operating System: Windows 7 Pro
Email Client: Outlook 2007 (SP2)
Linksys Router: WRT54G
Email Address: gmail.com
SMTP Setting: smtp.gmail.com (IMAP incoming)
SMTP Port: 587 (TLS encryption)
ISP: Cox

I removed all Outlook Add-ins.

I’m 99% sure this didn’t used to happen. Something must’ve changed, but I don’t know what. Any suggestions?
