I have the free/busy setup working ok.
Exchange users can see when zimbra users are busy/free and zimbra users can see if exchange users are busy.
However when a exchange user have the meeting planer up:
* when you mouse hover over busy for an exchange user you can see meeting subject
* when you mouse hover over busy for an zimbra user you don't see any details
is there any way the meetingplaner for an exchange user can view busy details for a zimbra user
