Applies to: Exchange Server 2013

This cmdlet is available only in on-premises Exchange Server 2013.

Use the Remove-MapiVirtualDirectory cmdlet to remove Message Application Programming Interface (MAPI) virtual directories from Microsoft Exchange 2013 servers. A MAPI virtual directory is used by supported versions of Microsoft Outlook to connect to mailboxes by using the MAPIHTTP protocol.

For information about the parameter sets in the Syntax section below, see Syntax.

Remove-MapiVirtualDirectory -Identity <VirtualDirectoryIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example removes the MAPI virtual directory from the local server named ContosoMail. All three commands do the same thing.

Remove-MapiVirtualDirectory -Identity "ContosoMail\mapi (Default Web Site)" 
Remove-MapiVirtualDirectory "mapi (Default Web Site)"
Remove-MapiVirtualDirectory mapi*

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 "Client Access virtual directory settings" entry in the Clients and mobile devices permissions topic.


Parameter Required Type Description




The Identity parameter specifies the MAPI virtual directory that you want to remove.

You can use any value that uniquely identifies the virtual directory. For example:

  • Name or <Server>\Name

  • Distinguished name (DN)

  • GUID

The Name value uses the syntax "<VirtualDirectoryName> (<WebsiteName>)" from the properties of the virtual directory. You can specify the wildcard character (*) instead of the default website by using the syntax <VirtualDirectoryName>*.




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 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.
