EDB mailbox recovery techniques

ExMerge is a free Microsoft tool that can be used to extract mailboxes from an EDB file. The extracted mailboxes can be saved in PST formats and then accessed using Outlook. It is a manual process that requires the access and applications of ExMerge utility.

  4. Click the Next button.
  5. Select the Step 1 Extract data from an Exchange Server Mailbox option.
  6. Click the Next button.
  7. Enter details of your Exchange Server to establish a connection with the EDB file.
  8. Click the Next button.
  9. Now select the EDB file.
  10.  Click the Next button.
  11. Now, you need to select the mailboxes that you want to extract as PST file.
  12. Select a location to save the extracted PST files.
  13. Click the Next button.
  14. The process will start.
  15. Once this process is completed, click the Finish button.


Benefits of this EDB mailbox Recovery technique

  • Free solution
  • Effective if you have a working connection with Exchange server


Disadvantage of this process

  • Lengthy
  • Needs technical skills
  • Time-consuming
  • You may incur data loss


Technique #2 – Using Exchange Powershell

Before we take you through this technique, we would like to mention that it is a very lengthy and complicated process. So, you should consider applying this process to perform EDB recovery only when you are

  •  a technical person
  • able to access Exchange server with sufficient admin rights
  • able to access and use PowerShell
  • well aware of the results of cmdlets being executed
  • ready to incur data loss

If you are not sure about any of the above-listed pointers, then the best solution for EDB recovery is using the Technique #3 given next in this article.

Perform the below steps to apply this process for EDB recovery:

  1. Login to your mail server.
  2. Access command prompt as an administrator.
  3. Perform dirty shut down on the EDB file to be recovered. You can use the below command to perform this action:
    eseutil /mh MyExchange.edb
  4. After dirty shut down is successful, execute the below command to repair the MyExchange.edb file:
    eseutil /r E02 /l "E:\EXDB12\Exchange Server\MyExchange\Logs" /d "E:\EXDB12\Exchange Server\MyExchange\File"
  5. Now, you need to create a recovery database. To do that, execute the below command:
    New-MailboxDatabase -Server mail01 -Name RDB1 -Recovery -EdbFilePath "E:\EXDB12\Exchange Server\ MyExchange\File\ MyExchange.edb" -LogFolderPath "E:\EXDB12\Exchange Server\MyExchange\Logs"
  6. Now, you need to mount the recovery database. To mount the database, execute the below command:
    Mount-Database RDB1
  7. Access the Exchange PowerShell and execute the below command to get a list of the mailboxes available in the EDB file:
    Get-MailboxStatistics -Database RDB1 | fl –auto
  8. Now, you need to restore these mailboxes on an existing Exchange Server. You can do this by executing the below command:
    New-MailboxRestoreRequest -SourceDatabase RDB1 -SourceStoreMailbox "Nav, S" -TargetMailbox newnavS –AllowLegacyDNMismatch
     In the above command, Nav, S is the name of the old mailbox that you will replace the newnavs, which is the name of the new mailbox.
  9. After the above command is executed, you need to check if the process has been completed successfully or failed. You can do that by executing the below command:
    Get-MailboxRestoreRequest
  10. If you see the status as completed after executing the command in step 9, then run the below command to remove the restore request:
    Get-MailboxRestoreRequest -Status Completed | Remove-MailboxRestoreRequest
  11. Now, you can export the restored mailbox to a PST file by running the below command:
    New-MailboxExportRequest -Mailbox navs -FilePath //loc/PST/navs.pst
  12. Now, again check the status of this command by executing the below command:
    Get-MailboxRestoreRequest
  13. If the status is completed, execute the below command:
    Get-mailboxexportrequest –status completed | remove-mailboxexportrequest
  14. Now, you can delete the original mailbox from which the PST is created by executing the below command:
    Disable-Mailbox navs@xyz.com
  15. Now, delete the recovery database by executing the below command on Exchange PowerShell:
    Remove-MailboxDatabase -Identity “RDB1”


Benefits of this technique to perform EDB recovery

  • Free technique
  • Works if executed properly


Disadvantages of this method

  • Complex
  • Lengthy
  • Chances of data loss are high
  • Time consuming
  • Strong knowledge of using PowerShell is must
