title: Get ALL Mailboxes via EWS (Exchange WebServices) - not my own but also shared and group mailboxes
body: <p>Can anyone provide me with a .NET (C# / VB) sample of how to get all mailboxes that I have access to ?</p>
  
  <p>I have only been able to get my OWN mailbox via EWS - not ALL THE OTHER mailboxes that I also have access to through Outlook. </p>
  
  <p>I don't have the names nor the id's of these mailboxes but isn't it possible to retrieve ALL mailboxes - including my own - that I am allowed to see - just as I can in Outlook ?</p>
  
  <p>I am using Autodiscover to get my mailbox like this: <a href="http://msdn.microsoft.com/en-us/library/dd634273%28v=exchg.80%29.aspx" rel="nofollow"><code>service.AutodiscoverUrl("xxxx@ee.dd")</code></a> - this will perhaps only get my own mailbox and not all the rest?</p>
  
  <p>Please help !?</p>
