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 (even before meeting time). 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 recipients did accept the meeting.

This is Outlook 2002 (XP) with exchange 2002.

Thanks
