title: How can I launch the Lync client from custom Android app via Intent?
body: <p>Our organization has Lync as primary channel for IM. Now that everyone is about to get a mobile phone we need a way to have the custom mobile apps display presence and initiate chat sessions. It is almost the way Facebook client does it with Facebook Messenger. </p>
  
  <p>I cannot find anything anywhere that shows how to any of those. I can deal w/o presence but it is a must to start the chat. </p>
  
  <p>Note I don't want to go against UCWA and write another chat client. Lync for Android is good enough. I just need to figure out what the proper Intent and parameters are.</p>
