Hi,
I just tried to register the onedrive plugin on my new installation of OMV7.7.2-1. After copying the authentication link to my browser, I was asekd to login with my Microsoft account and after that, I was told that the request can't be completed with the following error message:
unauthorized_client: The client does not exist or is not enabled for consumers. If you are the application developer, configure a new application through the App Registrations in the Azure Portal at https://go.microsoft.com/fwlink/?linkid=2083908.
Does anybody have an idea how to fix that?
