try deleting/renaming all files in C:\Documents and
Settings\username\Application Data\Microsoft\Outlook.

BTW, #7 is more effective than #3. :)

I have the sort of the same issue and it's happening on our Windows XP Pro
image that we're busy rolling out! Something happened with the last revision
of the image but we can't pinpoint it.

This is what happens:

*You open Outlook 2003 (all patches and SPs applied), you read your emails
and close Outlook. Outlook terminates fine.

*When you open Outlook 2003 and read your emails and open ANY attachment(s),
then close all attachments and close Outlook, then when you look in Task
Manager, Outlook.exe is still running.

If you don't End task Outlook.exe, when you try to log off or shut down the
system you get this message:

"End Program W"

Once you End that, another message comes up:

"Outlook.exe is not responding" and then you have to End it before the
system shutsdown or logs off.

I've tried to use filemon and regmon but I can't pinpoint it. Next I'm going
to try Hijack this.

Any suggestions on how to fix this would be greatly apprectiated!
