Calendar Locks up Outlook 2000

[Rick PUgh]

A user has Outlook 2000 connected to our Exchange 5.5
server. When he clicks on his calendar, it locks Outlook.
It is NOT a local problem. It acts the same when accessing
his account on other workstations. I believe it may be a
problem with his FREE/Busy or scheduled Tasks.
Both Win98 or Win2k say the appliction is not responding
but when the task is ended you can re-enter Outlook just
not Calendar.

Thanks
