title: Microsoft Graph API and shared calendar permissions
body: <p>I'm using the Graph Explorer on developer.microsoft.com to query shared calendars. 
  Example:</p>
  
  <p><a href="https://graph.microsoft.com/v1.0/users/user@my.com/calendarview?startdatetime=2018-04-19T19:25:06.250Z&amp;enddatetime=2018-04-26T19:25:06.250Z" rel="nofollow noreferrer">https://graph.microsoft.com/v1.0/users/user@my.com/calendarview?startdatetime=2018-04-19T19:25:06.250Z&amp;enddatetime=2018-04-26T19:25:06.250Z</a></p>
  
  <p>This works fine on calendars where I have Reviewer or Full Details access. Calendars where I have Free/Busy, subject, location, I get a 404 and response like this:</p>
  
  <p>{</p>
  
  <pre><code>"error": {
      "code": "ErrorItemNotFound",
      "message": "The specified object was not found in the store.",
      "innerError": {
          "request-id": "9f9e950f-038e-4411-b813-10a76d4b94fa",
          "date": "2018-04-19T19:42:48"
      }
  }
  </code></pre>
  
  <p>}</p>
  
  <p>I can open the same calendar with my Outlook client no problem. 
  My question is, are all of the different permission levels that you see in the Outlook client not supported by Graph? Or is there something I'm doing wrong?  </p>
