OL giving basic auth when logged in to Win as specific user


Outlook version
Outlook 2016 32 bit
Email Account
Office 365 Exchange
I'm getting the basic authentication prompt in Outlook when I try to connect to Ofice365.

I tried creating a new Outlook mail profile and have the same issue.
I created a new user login in Windows and get the modern authentication prompt as expected.

I tried adding these registry entries, but it didn't help

AlwaysUseMSOAuthForAutoDiscover =1

EnableADAL = 1
DisableADALatopWAMOverride = 0
Version = 1

What else can I try to get Outlook to connect under my normal Windows login?
