One of our users configured his Outlook to sent all his items (including
Calendar items) to a pst file. Seeing that this should not be done in the
company, I copied all the Calendar items back to his "main" Calendar.
However, now all his reoccuring meetings have a problem. If one of these
reoccuring meetings is cancel or changes are made to them, this user's
Calendar still has the meeting on his Calendar even after "remove from
calendar".

Any resolutions on this?
