Exchange Server backup issues

Recommended Posts



I'm trying to get Retrospect to backup our Exchange mailboxes but I don't seem to be having any luck. I've installed .NET 4.0 and MAPI/CDO 1.2.1 on the mailbox server as well as setting up the Retrospect mailbox account so the backup runs as that user.


Please see the log below:

Any help would be appreciated.
