Windows 8 mail services not working with SSL only, requires TLS


  • We use a hardware load balancing network device that does SSL certificate termination.  This SSL offloading "breaks" TLS communications.  In all past versions of Windows and Email clients this has not been an issue since you have the option to use SSL or TLS.  It seems that in Windows 8, TLS is always on no matter what settings you choose.  I'm testing with Live Mail 2012, the Mail App and Outlook 2010.  In Outlook 2010 SMTP settings you have the option to choose SSL, TLS or Auto.  No matter which setting I choose, the computer always attempt a TLS connection.  I verified this with a wireshark capture and by going directly to my CAS server and bypassing the load balancer.
