Managing the Exchange Virtual Server

The Exchange Virtual Server contains the virtual directories that provide access to Exchange for the HTTP clients that Exchange supports, such as Outlook Web Access, Outlook Mobile Access, and Exchange ActiveSync. Although you enable settings for Outlook Web Access, including forms-based authentication and gzip compression, by using the Exchange Virtual Server, you manage most settings for the Exchange virtual directories in the IIS snap-in.

Specifically, in Exchange 2003, if you need to configure authentication settings to your Exchange virtual directories, use the IIS snap-in. To configure access control for the \Exchange, \Public, and \Exadmin virtual directories, use Exchange System Manager instead.
