I recently migrated a client from SBS Exchange 2007 to Exchange 2013. In the process of migrating mailboxes, one of the mailbox moves failed. The mailbox that failed to migrate had too many corrupted items, Exchange 2013 would not take the mailbox becuase of the corruption. I had to recreate the users AD account in order to rebuild the mailbox. The EDB database are still sitting on the original server. I tried using data recovery software(Stellar EDB to PST, and Systools EDB to PST)both of these could not see the mailbox I was looking for. Any other suggestions?

Restore from an older backup.

Log into the mailbox and manually export the items to a .PST.  If you can get them into a .PST manually, you can then import that .PST.

You could also try an offline repair on a COPY of the .EDB.

Take a look at this reference ... http://blog.enowsoftware.com/solutions-engine/overcoming-corruption-during-mailbox-moves

While performing the migration, did you attempt to set the bad item limit to a high value?  Something like this...

New-MoveRequest -Identity "USERMAILBOX" -TargetDatabase “DATABASENAME” –BadItemLimit 1000 -AcceptLargeDataLoss

Open in new window
