HiI'm new to exchange and need some help solving a problem with a shared calender.I have a client that enters a recurring appointment into their shared calender. They will then go through and edit single occurances as needed. When editing a single occurance of the recurring appointment, upon saving and closing the whole series will disapear from the users calender (doesn't happen everytime, but often enough to be a serious PITA). The odd thing is that the recurring series is still viewable by other users when they look at the shared calender. So the data is still there, it's just not viewable by the user who owns the calender.Any help would be muchly appreciated.
