I have a user who has granted Delegate rights to his secretary so that she can read/create/modify appointments on his calendar. He has called me twice complaining that an appt. that the secretary/delegate added (via File | Open | Other user's folder) never appeared on his Calendar. Of course, when I check his machine, the appointments are there and I am unable to recreate the problem. I am not sure if it is a user error or what. Can anyone think of a reason that there might be some sort of "lag time" between the secretary putting an appt on his calendar remotely, and him being able to see it. We are on a Windows NT 4.0 system, running Exchange 5.5. I'll post this on the Exchange board to. Thanks in advance!
