Hello, we are running Exchange 2010 on a Windows 2008 domain. When setting up new Outlook clients (via Autodiscover), RPC/HTTP is configured with Basic Authentication. Is this setting coming from the autodiscover file? How can i change it so that it defaults to NTLM? Do i need to change something on the Exchange side? thanks.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
