Info of the LAN ;

1 Exchange 2003
All users with office 2003 and XP pro sp2

This error occurs only when 1 user sends an appointment to any attendies.
Here is the detail of the procedure ;

User X goes into his scheduler, makes an appointment, in the scheduling tab
adds attendees. Attendees receives the request in their mails and accepts
sending the response to User X. User X receives those responses fine but ;

All attendees (that accepted the meeting and sended the response) receives a
non delivery report saying that a user Y (which was a valid user but was
deleted since then) does not exist and to verify the e-mail address. This
comes from the exchange server.

So for a reason that I don't understant, when accepting a meeting from UserX
(only), outlook sends the reply to Userx fine and to UserY that does not
exist anymore. This only happens when userx sends a meeting request. When
sending normal e-mails to userx, there is no problem at all.

I'm sure it's something configured in outlook of userX but can't find
anything regarding userY.

Anybody has an idea?

Thanks
