All of my exch2010 services like OWA, ECP, ActiveSync, OAB are set to use Basic auth. I have a SSL cert on the CAS boxes but none of the IIS Virtual directories for these services are set to "Require SSL;" should this be set? I am also offloading the SSL to a loadbalancer so I assume not.
I want to make sure we do not have any non-ssl connections.. Whats the best practice for hardening exchange communications?
