How to enable TLS 1.1 and 1.2 RRS feed

  • Question

  • The  box    Windows Server 2008 SP2 64 bit      Exchange Server 2007 SP1

    I'm trying to enable TLS 1.1 and 1.2 on my Exchange server as well as the ciphers, but I have been unable to do so yet.   I have followed an example I saw and it didn't work

    http://www.derekseaman.com/2010/06/enable-tls-12-aes-256-and-sha-256-in.html 

    When I connect to my Exchange OWA page, its using TLS 1.0 and TLS_RSA_WITH_AES_256_CBC_SHA.  If I run a tester it shows that my server only supports TLS 1.0 and no other protocols.  I'm not sure where I'm going wrong on this. 

    Thanks,

    David

  • Hi Windows 2008 support only TLS 1.0 not 1.1 and 1.2, so it works OK. To use higher TLS protocols you must use at least 2008R2 SP1 or higher version of Windows server

  • Thanks.  That was it.  I guess I'll be moving my Exchange server at some point.
