Autodiscover service in Exchange 2016 and Exchange 2019 is possible because:Įxchange creates a virtual directory named autodiscover under the default web site in Internet Information Services (IIS).Īctive Directory stores and provides authoritative URLs for domain-joined computers.Ĭlient Access services on Mailbox servers provide authentication and proxy services for internal and external client connections. The Mailbox server now provides Client Access services, so you can't configure a standalone Client Access server like you could in previous versions of Exchange. Autodiscover works for client applications that are inside or outside firewalls and in resource forest and multiple forest scenarios.Įxchange 2016 introduced changes to services that were previously handled by the multiple servers. However, Autodiscover can also provide information to configure clients that use other protocols. For Exchange Web Services (EWS) clients, Autodiscover is typically used to find the EWS endpoint URL. The Autodiscover service minimizes user configuration and deployment steps by providing clients access to Exchange features.
