Getting this message whenever I try to sync my outlook calendar. 

I've followed all the steps on Azure with creating an app, I have the app client ID and the secret put into the admin settings page, and I've put in the username and password for the account I want to sync.

But then I get this message from Outlook (or from Odoo, not sure who's experiencing the issue)

Bad Request: Something went wrong during your token generation. Maybe your Authorization Code is invalid
