Hello, one of my users got a very persistent problem with Calendar
Synchronization; most of the time (not always) when he add an entry to the
calendar it will disappear within 30 seconds and when checking the Synch
error folder for the entry in question he gets following:
After disabling synchronisation ( Cached Exchange Mode) it is no longer
possible to add Calender entries but Outlook generates "Unknown error"
instead.
This is a Exchange server problem since the same problem persists no matter
which client we use so I wonder if the problem happens to be familiar?
