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.
- Basically you need to verify that you don't have anything using TLS 1.0 or 1.1 to connect to Office 365. Please refer to the following blog post about this matter: https://blogs.technet.microsoft.com/cloudyhappypeople/2017/12/22/the-end-of-support-for-older-tls-versions-in-office-365/
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/
