What is the Auto-Discover Service?
Auto-Discovery allows users to set up an account on a mail client that supports auto-discover with the email address and password. For most clients, the Auto-Discovery service requires Webmail to listen on HTTPS (443). A new CNAME or A record would be added to DNS. 'autodiscover.domain.com' should resolve to the server's hostname.
