This topic explains how to use the Exchange Management Console or the Exchange Management Shell to configure Basic authentication for Exchange ActiveSync. By default, when you install Microsoft Exchange Server 2007, 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.

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

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.
