Exchange databases gets corrupt due to various reasons, which makes them inaccessible. And users don’t even realize that their mailboxes are corrupt or consist of corrupt items. Repairing these mailboxes is very crucial, else you might end up losing your Exchange data.

Also, it is necessary to note that when a mailbox is being repaired in Exchange, mailbox access is disrupted, which means if you are performing a repair on a specific mailbox, it will be inaccessible by any user. To repair Exchange mailboxes from corrupt EDB files, Microsoft introduced a new feature in Exchange Server – New-Mailbox-Repair-Request cmdlet.

Using this cmdlet in Exchange Management Shell, you can quickly repair corrupt Exchange mailboxes. Following corruption errors and issues can be fixed using this command:

  • Search folder corruption errors (using Search Folder parameter)
  • Incorrect views on the folder (using FolderView parameter)
  • Aggregate counts on the folder that don’t reflect the correct values (using AggregateCounts parameter)
  • Provisioned folders that don’t point correctly to parent folders (using ProvisionFolder parameter)

Now, to use this command in Exchange Server, you need admin permission, else you will receive an access denied error message.

Using the New-Mailbox-Repair-Request cmdlet

After getting permission from the Exchange Admin, you can use the New-Mailbox-Repair-Request cmdlet to repair mailboxes. Below we have given a few examples of using this cmdlet.

  • To resolve Folder View corruption errors, use the below command. Running this command will detect and repair all folder views for the mailbox listed in the command.
  • New-MailboxRepairRequest -Mailbox User@domain.com -CorruptionType FolderView

  • To detect and repair corruption errors for a mailbox, including their archive mailboxes, use the following command:
  • New-MailboxRepairRequest -Mailbox User1 -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview -Archive

  • To detect and repair aggregate counts for the corrupted mailboxes, use the following command:
  • New-MailboxRepairRequest -Database DB01 -CorruptionType AggregateCounts

These commands will resolve most of the errors associated with your Exchange mailboxes. However, if the cmdlet doesn’t display any result for the mailbox after repairing, then you will have to access the event log application (under Source Exchange Server), where you will be able to check the repair status along with the Event ID.

Using this command, most of the mailbox corruption can be fixed, but it is not viable if the mailboxes are highly corrupt and inaccessible. In such cases, you need reliable software that can quickly repair corrupt Exchange mailboxes – Recoveryfix for Exchange Server Recovery.
