Some common reasons why Outlook will not shut down completely when you click
either the X or Exit:

1. PDA synchronization software with your PDA in the cradle.
2. WinFax Pro (especially 10.02 in Outlook 2003) - contact their support
for an alleged fix.
3. Franklin-Cover Plan Plus!
4. COM Add-ins.
5. Mail reminder add-ins that keep a stub of Outlook open in the background
to check for new mail and fire reminders.
6. Anti-virus/firewall programs that are set to scan incoming and outgoing
mail.

I would especially suspect a PDA with frequent synching going on.

After furious head scratching, Jan Groshan asked:

| It's very strange. When I close my Outlook 2000 SR-1, it shuts down
| and then, without warning, reopens! It will also happen if I am in
| some other program. Outlook will suddenly "take over" and switch me
| out of the program I am working on and into Outlook. HELP ! (It
| happened twice while I was tyring to post this message for help.)
