1.3 Overview
The Autodiscover HTTP Service Protocol allows a managed network (domain) to expose Autodiscover servers to clients that are configured with an email address.
This protocol provides a way for Autodiscover clients to find Autodiscover servers. The client starts with an email address of the form <local-part>@<domain> and expands it to a list of Uniform Resource Identifiers (URIs), any of which can be Autodiscover servers.
URIs for Autodiscover server locations can be published by using the following methods:
Service connection point objects, which can be queried by using the Lightweight Directory Access Protocol (LDAP)
Direct DNS configuration
DNS service (SRV) record configuration
Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS) 302 redirection
