Multi-factor Authentication breaks outlook

I WAS able to successfully get this to work finally, without wiping windows OS. Here is what I did.

First: I added the registry key per the below instructions (it wasn't there originally)(also, when I "ran as admin" the "Exchange" folder wasn't present, but when I opened normally {on an AD client} the "Exchange folder WAS there.)

Second: I removed Multi-Factor Auth for my user.

Third: I opened Outlook ---> Clicked File ----> Office Account ---> I signed out of all accounts (one user had 3, one user had only 1)

Fourth: Turned back on multi factor

Fifth: Opened Outlook and when I did - In one case I had to enter the App Password in the New Style App box. In the other case, Outlook just opened and worked. In both cases multi-factor is on and continues to work. Copied and pasted the key below. Hope that helps someone.
