You likely need to import and configure the Microsoft Graph Connector module in your Mendix project.
After that create an OAuth 2.0 authorization using your Azure app credentials.
Thanks Peter,
I've managed to wrestle my way through the Graph Connector Import (although I'm not clear on how I use that just yet) and have solved an issue about some layouts being missing but am now left with another couple of errors that say 'The selected parameter 'MicrosoftGraph.Rule_StatusCodeResponse_Unauthorized.HttpResponse' no longer exists.
I looked this up and found another community post about this and the author said they looked at the domain model and changed a few things but didn't expand on what they changed.
Any further insight sould be awesome.
Thanks!
