Calling resources on Trusted Application API for Skype Business Online shows CallbackUriUnreachable

Just checking if you did the step for tenant admin consent as this is the exception that we are seeing when we decode the X-Ms-ClientDiagnostics

OperationContext-OutgoingHttpRequestExceptionMessage=Could not get OAuth EVO token. Message: AADSTS50001: The application named https://events.gerirme.com.br was not found in the tenant named 989d053a-e8ab-4800-a4da-dbbf03b43ccb.  This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant.  You might have sent your authentication request to the wrong tenant.

Meanwhile I will try to pull logs off the server for this one and see if we have more information. We are working on improving debuggability for callback failures in general.

Will get back with updates. Thanks
