Azure Active Directory TLS 1.0, TLS 1.1, and 3DES deprecation

Hi All,

Greetings !!

As per the Microsoft announcement the below will deprecate, Here are my doubts.

1.If any of the servers are enabled with  TLS1.0/1.1/1.2 after 30June2021 there would be no impact as TLS 1.2 is still active or TLS 1.0 /1.1 need to mandate disable from the server ?

2.On the other hand which are the applications still using lower to TLS 1.2 will be impacted while Authentication

correct me if my understanding is wrong.

Kindly advice, Thanks in advance
