How do you recover one Exchange mailbox?

Question 1

If the user has deleted a few emails that they need you could have them try….?

Answer 1

In Outlook, on the Folder Tab, click “Recover Deleted Items.” Retention policy is
Exchange 2003 7 days
Exchange 2007 14 days
Exchange 2010 14 days

Question 2

Recover Deleted Items doesn’t work what next?

Answer 2

1. Using Exchange Management Console, find out which mailbox server the database of the current mailbox is on (ex. MAILBOX01)
2. Create a new temporary user with “(Recovered)” in the user name, with the mailbox located in the same database. “John Smith (Recovered)” in DB01.
3. Activate a recovery database on that mailbox server, MAILBOX01 in this example, by running this Exchange PowerShell cmdlet:
   New-MailboxDatabase -Recovery -Name RDB1 -Server MAILBOX01 -EdbFilePath “C:\mountpoints\rdb1-db\RDB1-DB.ebd” -LogFolderPath “C:\mountpoints\rdb1-log”
4. Perform the mailbox restore operation in the DPM (Data Protection Manager) console.
   Navigate to the Recovery space, then browse in the left pane to select the Exchange server name where the database replica resides (DB01 in this example). If you are using Exchange 2010 high-availability Database Availability Groups (DAGs), the replica will be listed in DPM under a mailbox server running a standby database copy, not the primary server where you created the recovery mailbox.

Select the recovery date and time from the calendar portion of the display. Locate the user mailbox in the Recoverable Item area, right click, and select Recover.
Choose to recover to an Exchange Server database, and type the name of the server and recovery database that are prepared for the restore, such as MAILBOX01 and RDB1.

Click through to complete the wizard and start the restore job.

5. When the DPM job is complete, run the following Exchange Powershell cmdlet to migrate the recovered mailbox content to the recovery user mailbox in a folder named “Recovery”:
   Restore-Mailbox -Identity ‘John Smith (Recovered)’ -RecoveryDatabase RDB1 -RecoveryMailbox ‘John Smith’ -TargetFolder Recovery
6. Next, extract the contents of the recovery mailbox to a PST folder to deliver to the user by running the following Exchange Powershell cmdlet:
   New-MailboxExportRequest -Mailbox JohnSmithRecovered -FilePath \MAILBOX01\RECOVERED.PST$\JohnSmith.Recovered.pst
   Tip: Pre-create the shared folder that will contain the PST file, RECOVERED.PST$ in this example. The folder needs to grant full access to the Exchange Trusted Subsystem group.
7. Deliver the PST file to the user, and delete the Active Directory account and mailbox of the temporary user “John Smith (Recovered)” in this example.
8. Finally, remove the recovery database created for this restore job by running the following Exchange Powershell cmdlet:
   Remove-MailboxDatabase -Identity RDB1
