Use the Remove-MailboxDatabase cmdlet to delete a mailbox database object.

Remove-MailboxDatabase -Identity <DatabaseIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

If the mailbox database has a database copy, the Remove-MailboxDatabase cmdlet also removes the copy.

The Remove-MailboxDatabase cmdlet removes only the database object from Active Directory. It doesn't remove the physical database files. You must remove the database files manually after you run the Remove-MailboxDatabase cmdlet.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Mailbox Database Permissions" section in the Mailbox Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the mailbox database to remove. You can use one of the following values:

  • GUID

  • Distinguished name (DN)

  • Name of the mailbox database




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
