Cant read one instance of recurring appointment
 

The problem we're having is a little different that what I've seen
posted. A user randomly gets the message "Cant read one instance of
recurring appointment. close any open appointments and try again, or
recreate the appointment" several times a day. When you click OK the
same message appears several times. Outlook doesn't indicate which
recurring appointment is having the problem and the message just pops
up at various times even if the user isn't in the calendar. We've
deleted the Frmcache file and run the clean profile switch, but that
hasn't worked. Has anyone seen this behavior before or know what's
causing it. We're using Outlook 2003 with Windows XP Professional and
Exchange 7.0.
