title: Integrate Microsoft Outlook labels in PHP application
body: <p>I've no idea where to start. My request is to point me at the right direction and provide me some keywords to help searching for solution. Forgive me the most probably inaccurate terminology I'll be using here - I'll try to explain the problem descriptively.</p>
  
  <p>In Microsoft Outlook and SharePoint, users' names are preceded by this ball showing their online/away/whatever status:</p>
  
  <p><img src="https://i.stack.imgur.com/gFzwP.jpg" alt="MSO user&#39;s label"></p>
  
  <p>The user's name is a hyperlink. When one points mouse cursor over the name, a label with more details pops up:</p>
  
  <p><img src="https://i.stack.imgur.com/tpPkb.jpg" alt="MSO user&#39;s details"></p>
  
  <p>I guess there's an API to handle this. How to implement that behavior into a PHP application? What API to use? Has the API a total-beginner guide?</p>

  <p>EDIT:<br>
  I want to replicate Outlook's functionality. I'd like the PHP app to display the same user's details label as Outlook and SharePoint do. The PHP app is working in the same intranet where Outlook and SharePoint. I'm hoping to find the information in the same source where Outlook and SharePoint do.</p>
