Do you have a Blackberry server? If so what version, what service pack, etc? There was some calendar issues with earlier versions of 4.1.
Also, are your exec admin team delegates and get copied on the exec meeting requests? If so, how many of them are in Cached Mode? If the admin team accepts/rejects a meeting request, it won't sync until their client does a Send/Receive (from my testing experience). Also, I have seen cases where something wouldn't get published or conflict. Also, they would also cause "Tentative" meeting requests. I had to change most of our admins to Online Mode in order to fix most of the problems (mainly with Resource Accounts).

Disappearing or duplicating calendar entries. I have Exchange 2003 sp2 and I feel should be patched. I do have an exec admin team that watch 10 execs calendars. I thought maybe there was a limit to how many people should look at or something to that affect. Thank you for any advice. David
