    Hi,

    As per my understanding, Your Domain Is Still Federated.

    Go to Entra ID → Custom Domain Names and check your domain.

    It will likely show:

    Authentication Type: Federated
    instead of:
    Authentication Type: Managed

    This happens because: Old lab used ADFS

    You created a new lab but synced the same domain name, Entra ID stored the old federation configuration, including metadata, Sign-in URL, and IssuerURI


    How to Fix the Issue: Convert Domain from Federated → Managed (recommended)

    Once you convert:
    Outlook autodiscover will stop redirecting to ADFS

Hi, 

exactly this I can see at my EntraID portal. THX

Right now I am struggeling a bit with the commands (https://learn.microsoft.com/en-us/answers/questions/2279288/how-to-change-from-federated-to-managed-domain) But I believe it has to do with my actual bulky internet situation.
