Authentication

Users can access the Microsoft Exchange Server computer through the Internet by logging on with a secure connection as a validated user or an anonymous user. When a user logs on to a Microsoft Exchange Server computer, an authenticated and encrypted session is established between the browser and the IIS computer. To gain access to Microsoft Exchange Server, the user's Windows NT domain account password must be validated before permission is granted to use the program and its data. This information is used by IIS to log the user on to the Microsoft Exchange Server computer.
