1 Introduction

The Autodiscover HTTP Service Protocol provides a way for Autodiscover clients to find Autodiscover servers. This protocol extends the Domain Name System (DNS) and directory services to make the location and settings of mail servers available to clients. This enables the clients to use the functionality specified in the Autodiscover Publishing and Lookup Protocol [MS-OXDSCLI].

Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
