I've been doing some testing with ZCS 4.5 and Entourage. Specifically, I'm looking at the calendar syncing.

I can get Entourage to pass appts to Zimbra, and Zimbra to Entourage. But, revisions to appts. made in the Zimbra web client don't seem to update Entourage. Neither updates in time frame for meetings or notes about meetings.

Any advice or thoughts?
