Outlook Crashing

Outlook crash after logging off and generating an error
message,”program error outlook.exe has generated errors and windows
will close down.”
Were are using MS Office 2000 SRv Pack1.
We used MS repair tool and still client Outlook 2000 got the error”program error outlook.exe has generated errors and windows
will close down.” the event viewer talked about IE 6. So I ran a repair tool on that and error still occured.
