Microsoft Entourage/Exchange Server problem: all objects disappeared from server - still in some form on the client

Question

One of our employees works with Entourage on his MacBook Pro (OSX 10.6) accessing Exchange Server 2007. Last Friday morning, I think while working over a VPN, Entourage (I think it was Entourage) deleted all his objects (mail, calendar, contacts) on the server and while creating a lot of strange folders (starting with underscores) on the client.

The local data seems to be there, but not in a consistent form. Since the user's mailbox is rather big, I suspect, that there was some kind of "move" operation which did not complete. I tried to export the data, but the export stops because of a corrupted object. Is there a tool or another way to export or retrieve the local data?

Edit - FYI: we solved the problem getting his data from the previous night's backup.

Answer 1

If you use the export-mailbox cmdlet, you can set a number of acceptable errors before the command is stopped and reported unsuccesfull. I would try and increase this number to see if that gives you a successfull export. (the parameter is -BadItemLimit).
