The Remove-OwaVirtualDirectory cmdlet removes Outlook Web Access virtual directories that are located in the Internet Information Services (IIS) Web site on a server that is running Microsoft Exchange Server 2007.


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


Parameter Required Type Description




This parameter specifies the name or GUID of an Outlook Web Access virtual directory. It is represented as: ServerName\VirtualDirectoryName (WebsiteName).




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




This parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory.




This parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, 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 parameter.

Detailed Description

To run the Remove-OwaVirtualDirectory cmdlet, you must specify the name of the Outlook Web Access 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 Access virtual directory that is deleted in IIS but is not deleted in the Active Directory directory service. These abandoned Outlook Web Access virtual directory objects are known as Active Directory orphans. We recommend that you remove this kind of Outlook Web Access virtual directory in Active Directory by using the Remove-OwaVirtualDirectory cmdlet.

  • You want to remove all legacy Outlook Web Access virtual directories from your native Exchange 2007 organization. The legacy Outlook Web Access virtual directories may have been created during Exchange 2007 Setup or manually created in an Exchange mixed environment.

  • You are troubleshooting an Outlook Web Access configuration issue that requires that you delete the existing Outlook Web Access virtual directory and then re-create the Outlook Web Access virtual directory.

  • If you uninstall the Client Access server role from the Exchange server, all Outlook Web Access virtual directories on that Exchange server are also removed.

The Remove-OwaVirtualDirectory cmdlet permanently removes an Outlook Web Access virtual directory or directories. When you use the Remove-OwaVirtualDirectory cmdlet, make sure that you do not accidentally delete a default Outlook Web Access 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. The account you use must be delegated the Exchange Server Administrators role and membership in the local Administrators group for the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
