Hi everyone,

I'm trying to create application that will communicate with D365 via OData. Some time ago I've retrieved a trial that was called like: https://trial-XXXXX.SANDBOX.operations.dynamics.com/.

There my AAD authentication was worked but environment is expired. I tried to retrieve one more and get a trial that was called like: https://trial-XXXXX.TRIAL.operations.dynamics.com/.

And on new environment the AAD auth doesn't work. I have an error 403: Forbidden. Please verify that the user is valid and set up correctly.

What can be wrong? Does trial support API auth? Or these names doesn't mean anything and both of them are trials?
