title: Skype for Business Web SDK - rejoining a conversation is not working
body: <p>The problem scenario is as follows:</p>
  
  <ol>
  <li>We create a Skype conversation via the SDK and add 3 or 4 participants, so that it becomes a Skype meeting with a conversation URI</li>
  <li>We save the conversation URI in our database so that we can rejoin if we disconnect</li>
  <li><p>The next day, when we try to reconnect to that conversation URI, we get an error: </p>
  
  <p><code>Error: The person or meeting doesn't exist.

  </ol>
  
  <p>We are following the online documentation and using the provided code example here: <a href="https://msdn.microsoft.com/EN-US/library/office/dn962176(v=office.16).aspx" rel="nofollow">https://msdn.microsoft.com/EN-US/library/office/dn962176(v=office.16).aspx</a></p>
  
  <p>It is this line which is throwing the error:</p>
  
  <p><code>conversation.chatService.start().then(function() {…});</code></p>
  
  <p>It's worth noting that this behaviour contradicts what is written in the documentation found here: <a href="https://msdn.microsoft.com/en-us/library/office/dn962151(v=office.16).aspx" rel="nofollow">https://msdn.microsoft.com/en-us/library/office/dn962151(v=office.16).aspx</a></p>
  
  <p>Specifically the part that says it will create a new conversation if it cannot find the existing one:</p>
  
  <p><strong><em>getConversationByUri</em></strong>
  <em>Finds an existing multi-party conversation model or creates a new one.</em></p>
  
  <p>Any help would be greatly appreciated!</p>
