On my Exchange Server 5.5 SP4 I have a mailbox that is assigned to an individual and who’s Calendar and Contact folder is owner permissioned to their secretary. The problem is with the Calendar folder. It contains 1297 entries. The mailbox owner can see and perform all operations on all the entries. When the permissioned user opens the Calendar folder the status bar indicates that there are 1297 records. If I change the view to category, and there are no records that have been categoried, the item count says that there are only 627 records. I have also verified, in other views, that sporatically throughout the folder records do not appear. If I change the users profile to open that mailbox directly all the items in the calendar are seen. Filtering is turned off.
