Unable to list Users from Graph: Authorization_RequestDenied

Question

Hi,

I'm having an strange behavior with an app.

Here https://learn.microsoft.com/en-us/graph/api/resources/users?view=graph-rest-1.0 say that I only need Users.ReadBasic.All to get the list. Permission was granted by the admin sometime ago. I see the scope in the JWT but I still get the "Insufficient privileges to complete the operation" error message when trying to access https://graph.microsoft.com/v1.0/users/ endpoint.

Strange thing is that it seems to happens only with new users in the tenant, the old ones seems to work fine.

Any ideas or suggestions?

Answer 1

1. Parse your token and make sure it has User.ReadBasic.All delegated permissions, ie "scp": "User.ReadBasic.All".
2. Make sure your account is a work/school account and not a personal Microsoft account.
