title: Outlook mailitem missing blank ConversationIndex and ConversationID
body: <p>I have some code that has been working until recently that used the mailitem ConversationIndex to track emails.</p>
  
  <p>All of a sudden all mailitems are being created with blank indexes and IDs.</p>
  
  <pre><code>myMail = CreateItemFromTemplate(sTemplatePath)
  debug.print mymail.ConversationIndex
  </code></pre>
  
  <p>Outputs blank!!!</p>
  
  <p>Any ideas what I've screwed up?</p>
