The Autodiscover service simplifies the provisioning of your mobile device by returning the required system settings after you enter your e-mail address and password. By default, the Autodiscover service is enabled in Exchange Server 2007.

The Autodiscover service provides configuration information to define the service binding in an Exchange Web service request. The discovery of the service binding enables the development of applications that can automatically reconfigure profile settings.
