    The only one that matter is: Authentication-results
    https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/anti-spam-message-headers?view=o365-worldwide

    You can ignore the "Original" header. that is simply stamped from the originating server and doesnt reflect the final results as the message was sent through the 365 transport systems.
