Was at a customer site when they needed to restore a mailbox from DPM 2012, no problem! DPM has some great features for those of you with Exchange 2013 on premise and can continually backup Exchange.
The issue that we ran into was that the DPM console was showing all of the mailbox databases as “Replica is inconsistent”. Running the consistency check would still result in the same error message. A quick look at the Exchange databases showed that it had been backed up recently by running the following command in Exchange Management Shell:
get-mailboxdatabase -status | fl *backup*
The fix was to install Visual C++ Redistributable for Visual Studio 2012 Update 3 (http://www.microsoft.com/en-us/download/details.aspx?id=30679) on the DPM 2012 server.
We then cleared the alerts in the DPM console and kicked off another consistency check and after that had run the backups were reading as OK and we could proceed with the restore.
There was no need to reboot the DPM server to apply the patch in our case but may it may require a reboot
