title: Doing batch requests in the office 365 email rest api
body: <p>I've found <a href="https://msdn.microsoft.com/library/office/dn903506.aspx" rel="nofollow">this link</a> that says that the Office 365 REST API supports batch requests.
  I have tried to use this to retrieve emails using the Office 365 REST API, but so far I receive a "400 - Bad Request" reply. Does this simply mean that the email part of the API does not support batch requests yet?
  In any case the only examples on the web are for Sharepoint I have found nothing about the Office 365 API.
  Any help would be appreciated.</p>
