title: Microsoft Graph API getSchedule endpoint for GCC High not working
body: <p>I am trying to hit /getSchedule endpoint for GCC High environment. I am getting error &quot;Resource not found for the segment 'microsoft.graph.getSchedule'&quot;.
  As per MS <a href="https://docs.microsoft.com/en-us/graph/deployments#supported-features" rel="nofollow noreferrer">docs</a> Outlook Calendar is supported in Microsoft Cloud for US Government.
  Same endpoint works fine against commercial O365 env - graph.microsoft.com
  Is this endpoint supposed to work in GCC High env or not? Am I constructing this wrong?</p>
