Hi, this is difficult to troubleshoot remote without knowing anything else about your environment. But I would remove those registry keys and "start over". You simply shouldn't disable these. Perhaps you should open a proper support ticket instead too.

    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
