I have a User viewing his outlook calendar via Entourage 2008 on his Mac.
we've had problems with appointments disappearing & doubling in the past, but this week his calendar has entirely disappeared now 3 times.
On the Windows side his Admin Assistant is using Outlook xp off our Exchange 2003 server.
Timing wise... (at least the 3rd time) it seemed like when he opened Entourage, the calendar disappeared soon after.
In the Event Viewer of the Exchange server we get numerous 8207 and 8230 event IDs.
Any help would be appreciated. There are so many Mac/Outlook Calendar posts out there... it's hard to locate a specific resolution to this.
