title: Office 365 REST API - Access meeting rooms calendars
body: <p>Using the Office 365 API, we'd like to allow users to view meeting rooms calendars and reserve them for events according to their permissions within Office 365.</p>
  
  <p>I understand it's possible with an Admin consent using a <a href="http://blogs.msdn.com/b/exchangedev/archive/2015/01/21/building-demon-or-service-apps-with-office-365-mail-calendar-and-contacts-apis-oauth2-client-credential-flow.aspx" rel="noreferrer">service app</a>, but this is not possible for all our use cases. We need to work with the user's actual permissions and not bypass them with the admin's permissions in the background.</p>
  
  <p>I also understood based on <a href="https://stackoverflow.com/questions/31055723/access-a-shared-calendar-such-as-a-meeting-room-via-office-365-rest-api">this question</a> and <a href="https://stackoverflow.com/questions/29628035/office-365-rest-api-list-resources-meeting-rooms">that question</a> that it was not possible to do so using the former Office 365 API. </p>
  
  <p>My question is whether it's now possible to do so using the new <a href="http://graph.microsoft.io/docs/overview/overview" rel="noreferrer">MS Graph API</a> and whether it's version 1.0 is stable for production use. If not, is it planned to be supported and when?</p>
  
  <p>Thanks!</p>
