What type of account? Are you using an Exchange mailbox or a Personal
Folders file for your delivery location? Have you tried Help>Detect and
Repair? Have you tried SCANPST.EXE if you are using a PST? Have you tried
the /cleanreminders command line switch? Have you tried the /safe command
line switch? If you've tried other things, please post those, too.
