Restore Disconnected Mailbox in Exchange Server in Simple Steps

There might be scenarios where a user may want to restore disconnected mailbox in Exchange 2016, 2013, 2010. First, a user may want to reconnect it to the same AD user account or to some other AD user account. Moreover, a user may wish to recover it to the newly created mailbox or to migrate it to the linked mailbox corresponding to the account which is outside the forest where the Exchange Server resides.


Methods to Restore Disconnected Mailbox in Exchange

When it comes to enabling disabled mailbox in Exchange Server 2016 which is either disabled or deleted, users can do that in two ways. They are as follows:

Using the Connect-mailbox command or the EAC

This procedure works by connecting the disconnected or disabled mailbox with the user account.
With the Help of Exchange Administrative Center – Users can implement the following steps to connect the disconnected mailbox. You can also reconnect disabled “shared mailboxes” or disabled “linked mailboxes” with the account of the user.
  • Open the EAC of Exchange Server and navigate to Recipients and then go to Mailboxes option.
  • Now, click on the More option and then hit Connect a Mailbox option.
  • This will list all the disconnected mailboxes in the Exchange Server.
Note: The disconnected mailboxes consists of deleted mailboxes, disabled mailboxes, and soft-deleted mailboxes.
  • Click on the disconnected mailbox and hit the Connect tab to reconnect the mailbox.
  • A prompt appears which assures that whether you want to connect the mailbox or not.
  • Select Yes option in the prompt.

Using the PowerShell Command

Second option to restore disconnected mailbox in Exchange 2016, 2013, 2010 is by using the Connect-Mailbox command in the shell. Moreover, you have to specify the type of the mailbox with which you are reconnecting. The syntax for executing the entire task is explained in the following segment:

Connect-Mailbox -Identity "XYZ" -Database MBXDB1 -User "XYZ"

This is the syntax for connecting a user mailbox. Here, the “Identity” and “User” parameters define the disconnected mailbox in the Exchange Server and Active Directory account respectively to restore disconnected mailbox in Exchange.

Connect-Mailbox -Identity "Robin Dexter" -Database MBXDB1 -LinkedDomainController KimFabriDC02 -LinkedMasterAccount Robin.Dexter@KimFabri.com -Alias Robin

The above command connects the “linked mailbox”. The “Identity”, “LinkedMasterAccount”, and “Alias” describes the disconnected mailbox if Exchange DB, the user account of Active Directory in the account forest which you wish to connect to the mailbox and the alias. Here, the alias is the part of email address on the left of the @ symbol of the email address.

Connect-Mailbox -Identity "Enterprise Shared Mailbox" -Database "Mailbox Database 02" -User "Enterprise Shared Mailbox" -Alias Enteshared -Shared

The above command displays an example to connect the shared mailbox.

Important Note: If a user does not specify the Alias parameter when the Connect-Mailbox command is implemented, the value mentioned in the “User” or “LinkedMasterAccount” will be used to create the email address alias for the reconnected mailbox.

Using the New-MailboxRestoreRequest cmdlet

This procedure works by combining the disables mailbox data with the existing mailbox data. This command uses the Mailbox Replication Service (MRS) to restore the Exchange Server mailbox data.
To create the request to restore Mailbox, a user has to use the display name, DN i.e. legacy distinguished name or the GUID of the mailbox which has been deleted. To show the values of the DisplayName, DN, and the properties of MailboxGUID of the deleted mailbox, the user has to execute Get-MailboxStatistics command.
For example, if you want to display the information for all the deleted, disabled or disconnected mailboxes, you have to execute the following command:

Get-MailboxDatabase | Get-MailboxStatistics | Where {$_.DisconnectReason -eq "Disabled"} | fl DisplayName,MailboxGuid,LegacyDN,Database

The following syntax shows the example to restore the deleted mailbox:

New-MailboxRequest -SourceStoreMailbox e448412-21-frzc123-4qwr4 -SourceDatabase MBXDB02 -TargetMailbox "Gabriala Kim" -AllowLegacyDNMismatch

This cmdlet will help you to restore deleted mailbox to the target mailbox. Here, the deleted mailbox which was located on the MBXDB01 mailbox is recognized by the ‘SourceStoreMailbox’. The ‘AllowLegacyDNMismatch’ helps to restore the source mailbox to the different mailbox. The mailbox should be the one which does not have the same legacy DN value.
