Meeting request lost and Meeting tracking not functioning

[Kenchr]

I have two issues going on with Outlook/Exchange.
1) Recipients of meeting requests lose the meeting after
accepting. Immediatly after accepting the meeting it shows
on the recipients calendar but eventually is lost. The
meeting is still showing on the organizers calendar which
brings me to Item #2
2) when a meeting organizer checks the tracking tab it
shows the response as NONE even though some if not all of
the recipients did accept the meeting.

This is Outlook 2002 (XP) with exchange 2002.

Thanks
