Our BES server has always been separate, the problem only seems to have occurred when we put in two new Exchange servers and removed one of the old ones i.e. we have gone from two to three Exchange servers.
The problem seems to occur when the meeting originator is on a different Exchange server to the attendee.
Iím not really a Blackberry administrator (just Exchange), is there anything that should be done on the Blackberry server after new Exchange servers have been added?
We have moved the Blackberry mailbox onto one of the new servers and reconfigured the MAPI profile to see if this helps but so far no joy.
