title: Identify bounced EmailMessage (EWS)
body: <p>Is there a way to accurately identity bounced back email notifications in a mailbox using EWS? So far I`ve looked at the message headers and nothing seems to indicate that the message is an email bounce notification.</p>
  
  <p>I also looked at the <a href="https://msdn.microsoft.com/en-us/library/microsoft.exchange.webservices.data.item_members(v=exchg.80).aspx" rel="noreferrer"><code>Item</code></a> and the <a href="https://msdn.microsoft.com/en-us/library/microsoft.exchange.webservices.data.emailmessage_members(v=exchg.80).aspx" rel="noreferrer"><code>EmailMessage</code></a> members and haven't found anything useful (I may have missed something).</p>
  
  <p>I could always parse the sender which always says 'Email Delivery System' or the subject line or even the message body, but I'm looking for a cleaner way to do that.</p>
