You can use the EMC or the Shell to configure Basic authentication for Microsoft Exchange ActiveSync. By default, when you install Microsoft Exchange Server 2010, Exchange ActiveSync is configured to use Basic authentication with Secure Sockets Layer (SSL) encryption. Other standard authentication methods include Digest authentication and Integrated Windows authentication. If you must return Exchange ActiveSync to Basic authentication, you can use the procedures in this topic.

Important:
If you configure Basic authentication for Exchange ActiveSync, we recommend that you require SSL for communications between mobile phones and Exchange ActiveSync. For more information about how to enable SSL, see Configure SSL for Exchange ActiveSync.
