EDB mailbox recovery techniques

If you are looking for a perfect solution to recover your exchange database file, then you’ve come to the right place.

Lets have a close look at some of the EDB recovery techniques :

Exchange database Recovery

1. ExMerge

ExMerge, although outdated, is a free to use utility from Microsoft that is capable of extracting mailboxes from exchange databases and saving them as Outlook PST. The PST files can then be imported into Outlook. Do keep in mind that ExMerge works with Outlook version 2003 only.

Using Exmerge

1. Open ExMerge and Click Next
2. Choose Extract or Import (Two Step Procedure) and Click next.
3. Choose the Step 1 Extract data from an Exchange Server Mailbox option and proceed.
4. Provide the exchange server details to establish connection.
5. Select EDB.
6. Select the mailboxes that you wish to export to PST.
7. Choose a preferred location to save the PST files and proceed
8. You can see that the process has now begun and once completed, ExMerge can be closed.

Advantages of ExMerge

Free and native utility

Works well when the connection to Exchange server is live.

Disadvantage

• Rather cumbersome
• Could require some technical know-how
• Slow process
• No guaranteed retrieval of all information

2. Powershell Method

There are some prerequisites to this method and it is better to know what they are before attempting exchange database recovery via powershell

• technical know-how is must
• Should be able to use Powershell with full admin rights
• Must be aware of what the cmdlets being executed actually do.
• Willing to overlook information losses that might happen.

If the above mentioned prerequisites seem a bit too much then there is another easier and more reliable way to achieve complete exchange recovery, see the third method mentioned here for more details on the same.

Steps for recovery

1. Login into mail server.
2. Open command prompt as an administrator and use the following command : eseutil /mh exchange-database.edb
3. Now use the below command to repair the exchange-database.edb file : eseutil /r E02 /l "E:\EXDB12\Exchange Server\exchange-database\Logs" /d "E:\EXDB12\Exchange Server\exchange-database\File"
4. Let’s now create a recovery database:

   New-MailboxDatabase -Server mail01 -Name RECDB -Recovery -EdbFilePath "E:\EXDB12\Exchange Server\ exchange-database\File\exchange-database" -LogFolderPath "E:\EXDB12\Exchange Server\exchange-database\Logs"

5. Thereafter, execute the following command to mount the recovery database:

   Mount-Database RECDB

6. To get a list of the mailboxes from the database, use the following commands:

   Get-MailboxStatistics -Database RECDB | fl –auto

7. To import the mailboxes from above steps to exchange server, use the following:

   New-MailboxRestoreRequest -SourceDatabase RECDB-SourceStoreMailbox "Dat, S" -TargetMailbox newdatS –AllowLegacyDNMismatch

   In the above command, Dat, S is the name of the old mailbox that you will replace the newdats, which is the name of the new mailbox.

8. Use Get-MailboxRestoreRequest to check the if the above command has been completed without any errors.
9. It is important that you remove the restore request as detailed below if Step * returns "Status Completed":

   Get-MailboxRestoreRequest -Status Completed | Remove-MailboxRestoreRequest

10. To export the mailboxes that have been restored to PST, use the following:

    New-MailboxExportRequest -Mailbox dats -FilePath //loc/PST/dats.pst

11. Repeat Steps 8 through 9 to check for completion of the above command.
12. To delete the original mailbox after PST creation, use:

    Disable-Mailbox dats@abc.com

13. Delete the recovery database using the following command:

    Remove-MailboxDatabase -Identity "RECDB"

Advantages of the above method

• Free and native
• Works fairly well if you’ve requisite technical skills.

Disadvantages

• Rather long and complex process
• Information loss is possible
• Time consuming
• User must be technically sound
