I am recieving errors when appointmant reminders pop up in Outlook 2003.  
when I click dismiss or snooze I get the error: "Cannot turn off the
reminder.  You May be reminded again.  Could not complete the operation.  One
or more parameter values are not valid."  I have recreated the Outlook
profile with no luck, I even uninstalled and reinstalled Office, and it
functions properly for a while then reverts back to the error.

Any help will be appreciated! Thanks.
