How to enable modern authentication for Office 2013

Recently, Microsoft has removed the basic authentication for all its Microsoft 365 services. Basic authentication is turned off for Exchange Online mailboxes on Microsoft 365 which means that if Outlook 2013 is not configured to use modern authentication, it loses the ability to connect.

To enable modern authentication for Office 2013, a Windows Registry setting must be implemented. This can be achieved manually by adding the following key:

The EnableADAL registry key referenced earlier must be created (Reg_DWORD) and set to 1:

HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity\EnableADAL = 1

A quicker way is by adding these code into a notepad, and save the file with the file extension .reg instead of .txt   :

Windows Registry Editor Version 5.00

I had a very weird problem connecting to my email this morning. It was my first time, and could not connect it for more than half an hour. I can connect to it on my home PC though.

Dig a quick Google and found these solution. Hope this helps you guys too :

Disable Modern Authentication by regedit to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity, create a DWORD item named EnableADAL and set it to zero.

Under the same registry key, create a DWORD item named DisableADALatopWAMOverride and set it to 1.

Received a complaint on this error yesterday. Managed to solved it after a quick google. Apparently someone forgot to close the file and did not even noticed it. So how you going to trace it between almost 50 users?
