A non-default Service name is configured on the Exchange AuthConfig. The configured Service name is '{0}'. The default Service name is '{1}'. Exchange publishes the current Service name in the Auth Metadata document and returns it as 'client_id' in a 401 bearer challenge response. Applications using OAuth to connect to Exchange must use the current configured Service name.
