Use the Remove-OwaVirtualDirectory cmdlet to remove Microsoft Office Outlook Web App virtual directories located in the Internet Information Services (IIS) Web site on a server running Microsoft Exchange Server 2010.

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

Parameter Required Type Description




The Identity parameter specifies the name or GUID of an Outlook Web App virtual directory. It's represented as: ServerName\VirtualDirectoryName (WebsiteName).




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.

To run the Remove-OwaVirtualDirectory cmdlet, you must specify the name of the Outlook Web App virtual directory that you want to remove. You might be required to use the Remove-OwaVirtualDirectory cmdlet in the following situations:

  • The Get-OwaVirtualDirectory cmdlet detects an Outlook Web App virtual directory deleted in IIS but not deleted in Active Directory. These abandoned Outlook Web App virtual directory objects are known as Active Directory orphans. We recommend that you remove this kind of Outlook Web App virtual directory in Active Directory by using the Remove-OwaVirtualDirectory cmdlet.
  • You are troubleshooting an Outlook Web App configuration issue that requires you to delete the existing Outlook Web App virtual directory and then re-create the Outlook Web App virtual directory.
    The Remove-OwaVirtualDirectory cmdlet permanently removes an Outlook Web App virtual directory or directories. When you use the Remove-OwaVirtualDirectory cmdlet, make sure that you don't accidentally delete the default Outlook Web App virtual directory. There are no default values for the Remove-OwaVirtualDirectory cmdlet.
    The Remove-OwaVirtualDirectory cmdlet supports the Confirm flag.

The Remove-OwaVirtualDirectory cmdlet can be run on any server that has the Exchange Server administration tools installed.
