I need the latest version available with basic email authentication (I think it's v13012), I'm trying to set up Oauth on my current version (v13011) but can't. I have been getting errors with the Connector URL.

We have seen the setup videos (https://www.youtube.com/watch?v=cwTpeIrflkQ&t=11s) and used the recommended URL ( https://outlook.office365.com/EWS/Exchange.asmx ), however we have not been successful. As of last Wednesday we are without incoming emails.
