Hi @Foxhunter:

[Tutorial] Connecting Frappe/ERPNext to Microsoft 365 mail services OAuth

We had App created from both the OAuth settings and Connected Apps. We deleted one from the OAuth page and kept the one from Connected Apps. Also make sure that, you are logged in with the same user and not as Admin. This shall work. Excellent work by Frappe with this connector.
