Exchange 2010 mailbox restore

Let's say you have a user who has accidentally deleted all her emails and you have no other way (but you should!) to restore them. Luckily enough, you have a full Exchange backup made by Windows Server Backup. Here is the fastest way:
1. Create C:\MyRec
2. Start WSB Recovery Wizard, select "Applications", "Exchange", select your relevant Exch backup and "Restore to other location" -> C:\MyRec
3. Navigate to your C:\MyRec\[..recovered folder..]\ mailbox folder, start an elevated command prompt and type eseutil /MH "Mailbox Database [numbers].edb"
3.a: If you  see a line "State: Dirty Shutdown" you have to do a eseutil /R E00 /i /d being in the mailbox directory above.
3.b: Do a eseutil /MH ... again and if you get a "State: Clean Shutdown" you are out of the water.
4. Unfortunately, you have to create a dedicated Recovery Database: Start an Exchange Management Shell and run: New-MailboxDatabase –Recovery –Name MyRecDB –Server MyTestServer –EDBFilePath C:\MyRec\[..recovered folder...]\"Mailbox Database [numbers].edb" –LogFolderPath C:\MyRec\[...recovered folder..]\
5: Bring online the new database with the GUI (Exchange Management Console): In the tree open Organization Configuration/Mailbox. You should see MyRecDB here with dismounted status. Mount it.


6. In the Exchange Shell, type: GetMailboxStatistics -Database -MyRecDB
7: Check if your username apears
8. Type: RestoreMailbox -Identity "Your username here from the list" -RecoveryDatabase MyRecDB and type Yes
9. Mailbox content of your user has been recovered into the root of her original mailbox. Problem solved. 

PS: I noticed that someone already made a more decent blog about this issue. I find it ubercool so you definitely want to check it out.

  1. Thanks for detail information about exchange server corruption. It is really very bad situation faced by the Exchange server administrators. It is true that eseutil /p repair method remove the corrupt or unrecognized items from database (.edb) file to bring the database into consistent state. However, there are some third party tools which rebuild the corrupt items and make the database consistent. Thus, users should take backup on regular basis to prevent data loss situations and also to handle the disaster situations efficiently. In the absence of valid database backup, it is good to use a third party tool like this: http://www.exchangeserver.pcrecoverytools.com/

  2. Nice Explainer. I've had good experience with EdbMails Edb to PST recovery tool - which provides a complete solution to recover Exchange Database (EDB) files. It is quick and uses deep scan to recover most data out of even corrupted databases.It supports public, private folder recovery. And also supports migration to Live exchange and Office 365. Archive mailbox migration is also supported by edbmails
