  Hello, with the help of Microsoft ticket, we resolved the problem.
  With our on premise servers, modern authentication was not possible, but the modern authentication was forced by a Windows Update beginning of February.
  
  We installed the package ExchangeModernAuthDisabled.ppkg and all works again !

    I am facing the same issue you got. let me describe what I understand and correct me:
    - ModernAuthentication is forced on Surface hub and need to be disabled?
    - No way to apply ModernAuthentication on on-premise server?
    - Can you advise on the steps to assign on-premise device account? normally I add the
    DomainName\email address removed for privacy reasons. by doing this , I am getting the error you mentioned.
