Not that I know of but I wonder if you've got more than one Calendar folder
(most likely in different PSTs).

You could try using the /cleanreminders command line switch described he

I just switched to a new XP computer and upgraded from Office 2003 to 2007
(keeping original settings and emails, etc intact). I am unable to use
reminders and tasks as pop-ups in 2007 - i can create appointments in my
calendar (which is not a sublisted calendar), and i can create reminders,
but
they don't happen. Does something happen to the personal folder calendar
when
upgrading from 03 to 07 that disables this feature?
