Hello,
I am configuring Exchange with a third party cloud email smart host for message hygiene. In reading the report on the traffic between the Exchange 2013 servers and and the smart host in the cloud, I noticed that the connection says it is using TLS 1.0. I was wondering if I can force the connection to use TLS 1.2, but without using the registry hacks to disable TLS 1.0 and TLS 1.1 all together. The remote smart host supports and is configured for TLS 1.2. The Exchange servers are running CU13, so they should be OK as TLS 1.2 support was introduced in CU8. Thanks!
