Maybe you can help explain what those keys do then? Why does disabling them fix the problem? Thanks!

haydenjohnson As I mentioned you'd be better off with a proper support ticket with Microsoft.

 

"Disabling ADAL or WAM authentication as a solution to fix sign-in or activation issues can have adverse effects in your environment and is not recommended."

 

These reg keys where common like 2018/2019, not needed now with updated OS and applications.

 

But I suppose here's what happens, not being an expert on the process.

 

EnableADAL 0 = you disable modern authentication (ADAL/OAuth)
DisableADALatopWAMOverride 1 = you disable WAM (Web account manager) and revert to ADAL for Outlook
DisableAADWAM 1 = you disable the Azure AD WAM process

 

WAM is the default token broker for W10 and is also associated with SSO/authentication.

 

You should instead use this if any. AlwaysUseMSOAuthForAutoDiscover 1 = force modern authentication
