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

Modified on Tue, 29 Aug 2023 at 04:46 PM

Kindly be advised that this tutorial may no longer align with the most recent updates and Microsoft's latest recommendations. If your current setup involves an older account operating with Exchange or Office365 with basic authentication, a fresh account addition is required in the Automatic Email Manager. Upon doing so, the system will identify it as an O365 account, enabling you to proceed with your previous action group or scenarios. 

Please note, if your use-case involves a shared email box, the process remains identical. You will need to add a new account using your shared email box. When prompted for Microsoft Authentication, please utilize your regular email to access the account. This completes the necessary steps.


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.
