title: Exchange Web Service find EmailMessage by "Message-ID" header
body: <p>I'm using the Java EWS library and try to reply to some messages. The main question is - how to find EmailMessage in folder or in mailbox if I only know value of "Message-ID" header of my message.</p>
  
  <p>I try to do something like this:</p>
  
  <pre><code>ExtendedPropertyDefinition p = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.InternetHeaders, "Message-ID", MapiPropertyType.String)
  
  myfolder.findItems(new SearchFilter.IsEqualTo(p, "&lt;1031208507.471.1446200157453.JavaMail.test&gt;"), new ItemView(1))
  </code></pre>
  
  <p>But result set is aleays empty! Can you help me? Some Java or C# solutions?</p>
