Actually, you may want to skip trying this branch just yet, I need to hammer on it a bit more.

Ok I did some further updates, it _might_ work now [oauth-test](https://github.com/firstof9/Home-Assistant-Mail-And-Packages/tree/oauth-test) let me know how it works out for you.

Thanks I'll keep hammering at it.

Ok looks like I cleared up those issues now, you'll need to repull the files. Thanks again for testing.

There should be an error in your `home-assistant.log` regarding this with more info.

I just pushed another fix, however, you have to register the app using the `Accounts in any organizational directory (Any Microsoft Entra ID tenant - Multitenant) and personal Microsoft accounts...

Ya that's as far as I get as well. From what I found searching it's because I don't have the Office 365 Exchange API stuff.

Seems I'll need to use another approach for this.

It's slow going, but I have a plan.

I'm still working on it when I have time.
