How to Allow the Use of an E-mail Address as the Logon User Name

 

Topic Last Modified: 2005-05-26

You can configure Exchange Server 2003 so that users can use their e-mail address as their logon user name. This is also known as configuring a user principal name (UPN) for users. After you configure a UPN on a virtual server that will be accessed for UPN authentication, users can authenticate by using user@example.com as their user name.

Before you perform the procedures in this topic, consider the following:

  • You must perform the procedure on all virtual servers and all virtual directories on each front-end and back-end server that users will access with UPN authentication.

  1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.

  2. In Exchange System Manager, expand Administrative Groups if administrative groups are enabled, expand Servers, and then expand the server where you want to configure the use of an e-mail address as the logon user name.

  3. Expand Protocols, expand HTTP, expand the virtual directory that you want to configure, and then select Properties.

  4. Select the Access tab, and then click Authentication.

  5. In the Default domain box, type a backslash (\).
