Ms. Orland: thanks for your prompt and accurate reply. Method 2 worked well.
Also thanks for the reminder to return to on line status. Now I have to
figure out why Outlook went into a loop and casued the problem in the first
place..
The most likely culprit is antivirus software. If it's configured to scan
incoming and outgoing email, it acts like a proxy between your mail servers
and Outlook. Your send/receive can suffer timeout issues as the AV takes time
to scan each incoming email and attached file, and again for anything
outgoing. If your send/receive interval is say 10 minutes and you're
receiving mail and trying to send out something large, you can see where AV
would slow the process down, then send/receive kicks in again when the first
tasks aren't complete and cause a loop, stuck email, etc. I hope that makes
sense to you. If not, please post back and ask for clarification.
Your best bet would be to remove the integration with Outlook from your
antivirus software or even uninstall it, then reinstall it omitting Outlook
integration. This won't compromise your security, your real time scanner will
catch anything it's updated for.
Other culprits can include, but are not limited to, antiSPAM software,
firewall, other security software.

I've been consistently having the same problem with E-mails that exceed 1-2
Mb. I have TrendMicro antivirus software which Kathleen suggests might be
the problem. I have Outlook set to send/receive every 15 minutes. Usually,
I will get a delivery failure within the first 2-minutes or so, while
receipents get multiple copies until I intervene.
I've never had this problem before on my old XP machine. Only now on my new
Dell with Vista home premium and Outlook-2007. My old machine also had
TrendMicro. I'd prefer not to do the uninstall of TrendMicro if I can avoid
it.
Thanks.
