Use the Remove-PublicFolderDatabase cmdlet to delete public folder databases.

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

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 "Public folder database" entry in the Mailbox Permissions topic.

Removing a public folder database can have a broad range of serious consequences. (This is particularly true when removing the last public folder database in the organization.) For more information, see Remove Public Folder Databases.


Parameter Required Type Description




The Identity parameter specifies a public folder database. You can use the following values:

  • GUID

  • Distinguished name (DN)

  • Database name

If you don't specify the server name, the command searches for databases on the local server. If you have multiple databases with the same name, the command retrieves all databases with the same name in the specified scope.




The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.




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




The RemoveLastAllowed parameter specifies whether to enable removal of the last public folder database in the organization.




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.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.

This example removes the database Public Folder Database after all the prerequisites for removing the database have been satisfied.
