How to switch Office365 account to modern authentication (OAUTH2)?

This tutorial is no more valid with latest version and with new Microsoft recommandations. If you are using an old account using Exchange or Office365 with basic auth, you have to add a new account in Automatic Email Manager, it will detect it as O365 account, then you can use your previous group of actions/scenarios.

Note: If you are using a shared email box, it is exactly the same, add a new account, use your shared email box, when it asks you for Microsoft Authentification, uses the regular email to log to the account, that's all. 

Important: If you are using Windows server, make sure you installed Microsoft Edge or Chrome instead of default Internet Explorer (IE), because Microsoft doesn't support anymore IE for authentification.
