Outlook Express Error code: 0x800ccc60

Last Modified: 2012-06-27
I have a client that is trying to send email using Outlook Express.  All configurations are correct, however when she tries to send email, Outlook Express gives the following error message:

The SMTP server returned an error. Account: 'mail.comcast.net', Server: 'smtp.comcast.net', Protocol: SMTP, Server Response: ' has too many connections (2) on sccrmhc12', Port 25, Secure(SSL): No, Error Number: 0x800ccc60.

I have looked this error message up all over, with no posted solution working.  I have disbaled the Anti-Virus (AVG) from scanning emails, and Comcast was of no help.  Does anyone know of a solution for this.  Thanks in advance for any help.

Thanks for the quick response...although I am just reading it this morning.  The sccrmhc12 is not always the same number...sometimes 11 or 10.  I will call Comcast and talk to a Tier 1 Tech today.  I'll keep you posted.  Thanks again.



It turned out to be a Comcast issue.  Their latest update to the email system has caused some unwanted errors only in Outlook, and Outlook Express.  Thanks for the help.  SInce you are the only one who replied to this case.....points are yours.  Thanks again.

Jfowlerjr, glad a Comcast Support Tech could help you.  Did you have to talk to a Tier 1 tech?

Found the problem after performing the following:

Running Repair for Outlook 2000
Uninstall Outlook 2000
Reinstalling Outlook 2000
Reinstalling SP2 for XPP
Uninstalling Antivirus
Uninstallling Spybot
Remove Account settings and create new one
Contacted ATT to check state of SMTP servers
Uninstalled all apps that may hook into Outlook
Change ATT port to 465 with SSL
Poured thru the web looking for answers that no one actually had.


The problem was that Outlook was trying to send a corrupt file out via SMTP from the OUTBOX that had a corrupt file in it. Once the Outbox was cleaned out, outbound mail started flowing again without errors. I kept settings at the port 465 with SSL for ATT DSL.
