We have several users that have been having some problems with
Outlook. After running for most of the day, Outlook will freeze when
trying to quit. If you just open and close right away, there aren't
any problems; it just happens when Outlook runs for several hours.
I've tried having the users run in Outlook Safe Mode, but the problem
still comes up.
