Zimbra with Entourage 2008
We've just switched from Kerio Mailserver to Zimbra Collaboration Suite for it's rich collaboration tool set (Chat, Documents, Files, etc.). While we were able to directly hook Entourage up to the Kerio Mailserver we cannot do this using ZCS. The iSync Connector doesn't really do any good (When we try to sync Entourage Calendars through the iSync Connector it only syncs a calender called Entourage and nothing else), because we have multiple and shared calendars and use the free/busy function of ZCS.
Is there any solution to this?
