This topic explains how to use the Exchange Management Shell to create an Outlook Web Access virtual directory in Microsoft Exchange Server 2007.

By default, when Exchange 2007 is installed, a new virtual directory named "owa" is created in the default Web site in Internet Information Services (IIS). Alternatively, when you run the New-OWAVirtualDirectory cmdlet in the Exchange Management Shell, a new virtual directory named "owa" is created in the default IIS Web site on the local Exchange 2007 server.

To create a new Outlook Web Access virtual directory, the following conditions must be true:

The local Exchange 2007 server has the Client Access server role installed.
There is a default IIS Web site, for example, /w3svc/1/root.
An Outlook Web Access virtual directory named "owa" does not already exist.

If you have to create a new virtual directory for Outlook Web Access, make sure that users are aware of the changes you are making. You will be interrupting mail flow for your users.

Important:
When the default owa virtual directory is created, both forms-based authentication and Secure Sockets Layer (SSL) encryption are enabled. However, when you create a new virtual directory by using the New-OWAVirtualDirectory cmdlet, FBA and SSL encryption are not enabled.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role.
