title: How does linkedin import contacts from outlook?
body: <p>Linkedin has a feature that allows users to enter their outlook credentials and imports their outlook contacts.</p>
  
  <p>I am trying to emulate this functionality, in a php application.</p>
  
  <p>So far, the only way I have discovered on how this might be done is through Exchange web Services.  <code>https://emailhost/EWS/Services.wsdl</code>  I am using the <a href="https://github.com/jamesiarmes/php-ews/wiki/Autodiscovery" rel="nofollow"><code>php-ews</code></a> library to try and connect to ews.  </p>
  
  <p>I was hoping for some sort of information on a defacto way to retrieve contacts given a users credentials, but have been unable to find much information on this at all.</p>
  
  <p>Are there any other ways that this could be accomplished other than EWS? Does anyone know how linkedin is doing this?  </p>
