I am runing Microsoft Office Professional 2007 on Vista Home Premium. All
programs work perfectly (including Outlook) except every time I close
Outlook I get the following message.

"Microsoft Office Outlook has stopped working."
"A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available."

When I click on Close Program, the error box goes away. Other than the
error message upon closing Outlook, the program works fine.

I have run the office diagnostics and inbox repair tool to no effect.

Any thoughts would be appreciated.
