So let's say I have everyone using Zimbra desktop. Then the server crashes. Say there's not even a very good backup, or it's a day old and I don't want to go back that far. That shouldn't be that bad, since everyone's got a local copy of their messages (and contacts, calendar, etc.) with Zimbra Desktop. However, when the new server comes online, is there any way to make sure that Zimbra Desktop doesn't go "oh, look at that, the server's mail store is blank" and proceed to delete everything in its local store (and instead reverse-sync local store back to the server)?
