SUMMARY

This article describes how to set up Microsoft Outlook Web Access (OWA) to accept user principal name (UPN) logon names (for example, someone@microsoft.com or someone@example.com) for Microsoft Exchange 2000 Server through a front-end server or to a back-end server.

MORE INFORMATION

To set up OWA to accept UPN logon names for Exchange 2000 through a front-end server or to a back-end server:
  1. Start Exchange System Manager. To do this, click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Expand Servers, expand ServerName, expand Protocols, expand HTTP, and then expand Exchange Virtual Server.
  3. Under Exchange Virtual Server, right-click the Exchange virtual directory, and then click Properties.
  4. Click the Access tab, and then click Authentication.
  5. Click to select the Basic authentication check box, if it is not already selected.
  6. In the Default domain box, type \ if it is not already present, and then click OK to close all dialog boxes.

    Note In Microsoft Windows XP the Domain Name field is on the same window where you select Basic Authentication.
  7. Click OK, and then click OK again to return to Exchange System Manager.
  8. Repeat this procedure for the public virtual directory under Exchange Virtual Server.
  9. Repeat this procedure for the other front-end and back-end servers.
Note This information is from the Exchange System Manager Help.

When you complete these steps, you overwrite the default domain because the DS2MB service replicates the default domain in Exchange 2000.
