Rules and Examples to create a Restore request

Rule 1 – To create a Restore request, you must provide the DisplayName, LegacyDN, or MailboxGUID for the server’s mailbox that has been soft-deleted or disabled.

Example 1 – In this example, the Get-MailboxStatistics cmdlet is used to restore or return the DisplayName, LegacyDN, DisconnectReason, and MailboxGUID for all mailboxes on mailbox database ‘MBD01’ that have a disconnect reason of SoftDeleted or Disabled.


This example returns the source mailbox with the MailboxGUID 1d20855f-fd54-4681-98e6-e249f7326ddd on mailbox database ‘MBD01’ to the target mailbox with the alias Aisha.


Example 2 – This example restores the data of the source mailbox with the DisplayName of John Smith on mailbox database MBD01 to the archive mailbox for    


Now comes the description in detail

Exchange Server does not delete the mailbox from the source database immediately in case the mailboxes are moved from one database (source) to the other (destination) database. Instead, what happens after the completion of the ‘move’ process is that the source database mailbox is switched to a soft-deleted state. With this, the mailbox data can be accessed during the operation of mailbox restore by using the New-MailboxRestoreRequest cmdlet set in Exchange Server. The soft-deleted mailboxes in the database remain in the source database until either the retention period of deleted mailbox finishes or you use the Remove-StoreMailbox cmdlet to remove the mailbox from the source database.

To view the mailboxes that have been soft-deleted from the database, you would have to run the Get-MailboxStatistics cmdlet against that database. Here, you would have to look for results that have a DisconnectReason with SoftDeleted value.

Note: The mailbox will not be marked ‘disabled’ until the Exchange Information Store service determines that Active Directory has been updated with the information of the disabled mailbox. The speed of the process can be increased by executing the Update-StoreMailboxState cmdlet against that database. 

Disabled mailboxes in the mailbox database are retained for the time as it is specified in the ‘deleted mailbox retention settings’ configured for the particular mailbox database. After the specified time, the mailbox is deleted permanently.

To view the ‘disabled’ mailboxes, the cmdlet should be run against the database. Then, you should look for results that have a DisconnectReason with ‘Disabled’ value.

Note – To execute ‘Get-MailboxStatistics’ cmdlet, you need to have permission for it. However, you may not have access to some parameters if they are not included in the ‘permissions’ given to you.
