Rebuild failed Exchange Mail Database


As a short opener; I was in the process of moving old mailboxes to a VHD drive on a NAS when the NAS failed. The move had not completed.  I have managed to get off from the NAS the backup mail pst's  but now I need to understand how to put Exchange right as I can't seem to run backups at the moment from Exchange - I think due to some sort of maintenance mode.  (OS is SBS 2011 - Exchange 2010)

So, currently, I have a Mail Database pointing to a volume that is no longer connected.  All I want to do is move the mailboxes (about 10) back to the original DB or another, I don't mind, so that I can stabilise Exchange.  Once working properly I will then move to a local partition rather than a VDH.

Can anyone provide a step by step to recover?  I was thinking of just deleting the  MDB but I don't want to make matters worse - it's been bad enough...!

Thanks.  I'll try tonight.  The mailboxes are still marked as being moved.  I presume after deleting the mailboxes I should delete the Mail Database they were being moved to and which is now dismounted.
Will post an update tonight.

Do you have a backup of the database
TMSAuthor Commented:
The short answer is yes, in that I have a backup of the the Exchange database before I created a new Database and submitted the move request.  Thus, if I restore I will mess up the database with all the live Users in which I would rather avoid.  I haven't lost any data as I have pst archives of the mailboxes I moved.

I bought an Exchange Admin last night last night and it suggests using a cmd line to just move the db location, without putting in a DB move request via the EMC, and pointing to a new folder path.  I presume Exchange will then build a new store and the mailboxes will be empty which is fine as I can import the psts if needed.

I'm uncertain as to the relationship between the mailboxes and the db.  What would happen if I just put in a mailbox move to a mailbox that had a dismounted db?

Delete the mailboxes of the users that you are trying to delete.
Create emapty mailboxes for the user and import and mail from the PSTs that you have.

Thanks again. I deleted one mailbox and then it wouldn't let me do any more.  After a couple of hours it did so all were deleted then I deleted the mail db.  Only thing is that when I deleted the mailbox SBS2011 deleted the Whole User account.  I recreated mine but it has of course created a few linkage issues but the server seems fine and I successfully exported a mailbox to a pst from the backup software.  So all good, other than the new px2-300 I bought to replace the ix-200 that failed also failed to turn on.....!!!!!!  EMC said its a failed firmware issue so back to the shop for that..
Much appreciated.
