Office365 Authentication Error

Copper Contributor

We are on a bit of storm lately due to TLS 1.0 and 1.1 being retired.

All our clients are experiencing a disconnection / authentication failure.


This was the link on a pop up error.


We got 2 Windows Server. Ad-connect (2012 R2) and Domain Controller (2012) and windows 10 client

I followed the instruction Update 3140245

Download and install dot net


I add registry for TLS 1.2 using this (both client and servers)


But still nothing.

I am manually checking TLS 1.2 in advanced settings from internet options and it works (temporarily) but windows 10 automatically unchecking this options. 


Can anyone tell me if i miss or done something wrong ?

Just Microsoft hack, did you reboot after registry changes.
