I have recently implemented a new server 08 install at a client facility. They have moved from exchange 2003 to exchange 2010.
Before the problem began, User A would create an appointment on their outlook calendar and invite User B. User B would be able to edit the time/date of the appointment on their Iphone or Ipad.
Now User B can accept or deny the appointment, but cannot edit it.
User B can however edit appointments created by themselves on these devices.
User B does have editing permissions on user A's calendar within outlook.
User B CAN edit these appointments within outlook, just not on the phone or ipad.
Any help would be appreciated.
