OAuth app based authentication RRS feed

  • Question

  • Sorry if I am posting in the wrong section. if this is the wrong forum, can please direct me to the correct forum.

    We setup a vendors application OAuth app based authentication in Azure.  From time to time, the error message ("...(401)Unauthorized") appears on the vendors portal. We are purely O365, AD on-premise with AAD. 

    I don't know what could be wrong or where to look from O365 side. 

    Can you please advise.
