Outlook 2007 says it sent e-mails but they are never received

[Mike]

I am running Win7 with Office 2007 and I use Outlook for my e-mail and
Comcast is my provider.

over the last 2 months, I have had to delete my e-mail account and re-do it
in Outlook because I can receive e-mail but cannot send it. Outlook says it
was sent and it appears in my sent folder but it is never received. I test
this by sending an e-mail to my live.com account. Comcast says it is not
them. this all started with a recent update from Microsoft and Comcast
changing from Macafee to Norton. I have turned off the outgoing e-mail scan
in Norton.

any help would be appreciated!!

This makes it not an Outlook problem. Outlook received word from the server
that the message was delivered. Outlook has no choice but to believe it.
That server can be a real SMTP server or it can be the shim in your AV program
that's pretending to be the server and accepting messages from Outlook so they
can be scanned and then passed on to the real server.

I test
this by sending an e-mail to my live.com account. Comcast says it is not

Turning off the mail scanning may not be enough, particularly with Symantec
products. You should uninstall it completely, reboot, and reinstall it
without the mail scanning feature.
