 ## DESCRIPTION
 Partner applications authorized by Exchange can access their resources after they're authenticated using server-to-server authentication. A partner application can authenticate by using self-issued tokens trusted by Exchange or by using an authorization server trusted by Exchange. You can use the New-AuthServer cmdlet to create a trusted authorization server object in Exchange, which allows it to trust tokens issued by the authorization server.
