Greetings,
We're trying to roll out TLS 1.2 in our test environment and can't seem to get Exchange to work with the protocol.
We've been using this method to enable TLS 1.2 (and disable the other protocols - TLS1.0, SSL2.0, SSL3.0, PCT1.0): http://www.adminhorror.com/2011/10/enable-tls-11-and-tls-12-on-windows_1853.html
We originally tried using Exchange 2010 on 2008 R2, but then I ran across this article saying that it is not supported: http://support.microsoft.com/kb/2709167/en-us
We've since tried to set it up with Exchange 2013 on Server 2012. Still no luck. The only time Exchange wants to work is when TLS1.0 is enabled.
I suspect that TLS1.1 and TLS 1.2 are also not supported on Exchange 2013, or that I'm changing the wrong registry keys, but I wanted to find confirmation. I've searched extensively and can't find any documentation leading me to believe one way or the other if it's supported.
Any help or insight would be greatly appreciated. Thanks!
