Detailed Description

The Set-OwaVirtualDirectory cmdlet is used to modify the settings of Outlook Web Access virtual directories on a computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed. Running the Set-OwaVirtualDirectory cmdlet lets an administrator enable or disable features and manage security.

Note:
The Identity parameter is required by the Set-OWAVirtualDirectory cmdlet.

Before you run the Set-OwaVirtualDirectory cmdlet:

You must have Write access to the virtual directory objects in the Active Directory directory service. If you do not have the necessary permissions and you try to run the Set-OwaVirtualDirectory cmdlet on the Active Directory virtual directory object, the cmdlet will fail.
You must have Write access to virtual directory objects in the metabase for some of the properties such as Authentication and GZip. If you do not have the necessary permissions to run the Set-OwaVirtualDirectory cmdlet on a metabase virtual directory object or on a parameter that writes to the metabase, the cmdlet will fail.
Before you run the Set-OwaVirtualDirectory cmdlet, verify that the data source can be read. Depending on the properties that you want to set on an Outlook Web Access virtual directory, you may want to run the cmdlet in a test environment on the Outlook Web Access virtual directory object in Active Directory, the metabase, or both.

The Set-OwaVirtualDirectory cmdlet can be run on any server that has the Exchange Server administration tools installed. To perform the following procedure, the account you use must be delegated the following:

Exchange Server Administrator role and local Administrators group for the target server

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

Notes About Forms-Based Authentication

Any time forms-based authentication is turned on or off, you must use the IISReset /noforce command before the change will take effect.
To switch from forms-based authentication to Basic authentication, you must first turn off forms-based authentication, and then, as a separate task, turn on Basic authentication. You cannot turn off forms-based authentication and turn on Basic authentication in a single task.
