Hello, i have implemented the example to access an rpmsg-Message file (https://github.com/Azure-Samples/MipSDK-File-Dotnet-ServicePrincipalAuth). I have configured my MS Entra correctly, registeresd an app with application delegation access as it was described in the readme. But when i call "CreateFileHandlerAsync" i got an AccessDeniedException: The service didn't accept the auth token. Challenge:['Bearer resource="https://aadrm.com" ..... What can I do? What can be wrong configured? I have also booked an additional service (Enterprise Mobility + Security E3) to my Microsoft 365 Business Basic. Or must i have an other License? Regards Nico

Have you registered your client app in Entra ID as below ?:
What is the scope you are using? use https://aadrm.com/.default as scope instead of https://aadrm.com

2024-03-01T21:45:24.36+00:00 Hello @Givary-MSFT ,
thank you for response.
Yes, i have registered the client app correctly. Now i have found someting. I can decrypt rpmsg-Messages with the MIP-SDK when the mail is an internal mail. When i get an external protected mail (from another office365 tenant) i can't decrypt and get the error message described in my first post. Is it generally not possible? Oulook can display this external proteced message so i think it should work somehow.
Regards
Nico
