Convert EDB to PST With PowerShell Cmdlets
EDB files are a database contains mailboxes of each and every user of Exchange Server. Sometimes, EDB got damaged and administrator needs to recover it and export Exchange mailboxes to PST as per their need. Microsoft provides built-in methods to recover mailbox from EDB file and convert it to PST. In this article, I will shed some lights on steps to recover & convert EDB to PST using PowerShell.
Steps to Convert EDB file to PST file
Step 1: Open elevated command prompt. Run eseutil /mh MDB01.edb to check status of database if it was dirty shutdown.
Step 2: Run eseutil /r to repair Exchange database. Execute the following cmdlet:
eseutil /r E02 /l “E:\EXDB12\Exchange Server\MDB01\Logs” /d “E:\EXDB12\Exchange Server\MDB01\File”
( where E02 is the file name of check file)
Step 3: Now create RecoveryDB with the following command:
New-MailboxDatabase -Server mail01 -Name RecoveryDB1 -Recovery -EdbFilePath “E:\EXDB12\Exchange Server\MDB01\File\MDB01 .edb” -LogFolderPath “E:\EXDB12\Exchange Server\MDB01\Logs”
Step 4: Once RecoveryDB is created. Its time to mount it. Run the below command to do the same:
Mount-Database RecoveryDB01
Step 5: Run the following command to get a list of mailboxes:
Get-MailboxStatistics -Database RecoveryDB1 | ft –auto
Step 6: Run New-MailboxRestoreRequest to Restore mailbox to an existing user
New-MailboxRestoreRequest -SourceDatabase RecoveryDB1 -SourceStoreMailbox “Nik, Smith” -TargetMailbox newuser –AllowLegacyDNMismatch
Note: Where “Nik, Smith” is a mailbox which need to be restored from the old database and “newuser” is a new mailbox you just created.
Step 7: To check the status of a restore request, execute the below command:
Get-MailboxRestoreRequest
Step 8: Once status gets completed, remove restore request with the following cmdlet:
Get-MailboxRestoreRequest -Status Completed | Remove-MailboxRestoreRequest
Step 9: You can convert EDB to PST PowerShell using New-MailboxExportRequest cmdlet as given below:
New-MailboxExportRequest -Mailbox niksmith -FilePath //fileshare01/PST/niksmith.pst
Step 10: To check the status of export request, execute the below command:
Get-Mailboxexportrequest
Step 11: Once the status of export request gets completed, remove export request with the following cmdlet:
Get-Mailboxexportrequest -status completed | Remove-Mailboxexportrequest
Step 12: Delete data from mailbox it was imported to
Disable-Mailbox Nik.Smith@domain.com
Step 13: Delete Recovery database with the following cmdlet:
Remove-MailboxDatabase -Identity “RecoveryDB1”
Then manually delete the file from its location (database and log).
