Try running outlook using the safe switch
Run
Outlook.exe /safe (note space between exe /)
Does it still exhibit the same behaviour? if not it would appear an addin
has not been removed (Com addins)

Sorry. I didn't see any reply to my first post, so I thought I was in the
wrong section, so I posted again. I'll just have to learn to be more
patient.

I'm running Office XP Standard on Windows XP. After I downloaded
iTunes,
outlook stopped dead. I can't send or recieve, add contacts, print
calenders, etc. Whenever I click on a button I get one of two error
messages. "The operation failed", or "The messaging interface has
returned
an unknown error. If the problem persists, restart Outlook." I tried
that,
downloaded many upgrades, SP3, etc., and tried the repair disc. I also
removed iTunes. Nothing seems to work. Any suggestions would be
greatfuly
appreciated.

No need to ask more than once.
