Hello Team

when i try connect the outlook 2010 with exchnage server 2016, its not connecting and not creeating the outlook profile. i know outlook 2010 supports TLS 1.0 or TLS 1.1 which is not compatable with exchange 2016 server.

am doing some test and R&D on TLS 1.0 and TLS 1.1 in my test environemt. As i dont havve an application which support the legacy version of TLS 1.0 and TLS 1.0 , iam using outlook 2020.

i want to learn the TLS algarithm and enforce the TLS 2.0 in my exchnage server 2016.

should i create any cleint registry under TLS1.0 , TLS 1.1 to make use and connect of outlook 2010 with exchnage server 2016

What are the registry should i add in exchnage server and clinet PC

    Outlook 2010 with the latest updates is fully supported with Exchange 2016 . If its not working, you have a different issue:

    Hi @Ramki

    Have you checked if you could access the Exchange mailbox using different version of Outlook? Using ExRCA to test the outlook connectivity.

    Here is a related article introduces about OUTLOOK 2010 DISCONNECTED WITH TLS 1.2, you could check if the troubleshooting steps in the link works for you.
