title: Export an EmailMessage from EWS that can be opened in MS Outlook
body: <p>I'm writing an application that monitors an Exchange mailbox using EWS. It saves the attachments of the incoming mails to a network folder.</p>
  
  <p>These files are then used by a 3d party application.</p>
  
  <p>Now I've been asked if it is possible to not only save the attachments but the entire e-mail with attachments still included so it can be opened in Outlook. (no other mailclients need to be supported).</p>
  
  <p>The Exchange server is <code>Exchange 2010</code> and the application is being written in <code>C#</code>
  Can this be done using EWS? Or is my only solution to use Interop.Outlook to create a .msg file?</p>
