Preparing Exchange 2010 Hybrid for TLS 1.2
I have an Exchange 2010 SP3 RU16 Hybrid/365 environment. I'm a little confused as to what exactly I need to do to ensure my 2010 server continues to communicate with my tenant on March 1st.
At this point, you have to wait for Exchange 2010 SP3 RU20 to be released. There is more detailed guidance here: https://blogs.technet.microsoft.com/exchange/2018/01/26/exchange-server-tls-guidance-part-1-getting-ready-for-tls-1-2/
