title: How to get attachment by id using EWS Managed API?
body: <p>Is it possible to get attachment with EWS Managed API directly, without getting its containing EmailMessage first?</p>
  
  <p>Something like:</p>
  
  <pre><code>FileAttachment attach = FileAttachment.Bind(ewsService, attachId);
  </code></pre>
  
  <p>I couldn't find any method for this.</p>
