I'm looking at deploying Zimbra. The most important functionality we would be using is the shared calenders. We are a accounting office, so our scheduling is mission critical. I am trying to figure out some type of automated system to sync/backup the calendars locally so that if the internet line / remote server went down, we would still be able to access our calendar system. I see that the outlook connector doesn't currently support shared calendars. Can anyone suggest the best way to do this? The Zimbra server will not be hosted locally, it will be at a hosting center.
