    Thanks Joyce for your response.

    After going through the SEND and RECEIVE log in detail, I finally figured out something.

    The installation of Exchange 2010 comes with 2x self-signed certificates.
    One of them is used for Web Management and another one is for communication with other fellow Exchange Servers.  

    The TLS 1.2 communications I saw are between fellow Exchange Servers like between Edge and CAS servers.
    I also saw TLS 1.2 communicatons between my Edge Server and mail.protection.outlook.com

    So, definitely TLS 1.2 is running even though I did not make any change.

    Hi,

    According to your information above, the value of "Enabled" seems not setting correctly. The value should be 1

    Did you set the value before? You may have edited it already.

    The default value should be like the below

    For more information: EXCHANGE 2010 AND TLS 1.2
