title: Get Global Address List (GAL) from Exchange Server 2010 SP1 using ExchangeService
body: <p>I want to programatically (using C#) access to the Global Address List on exchange, using ExchangeService WebService. How can I do that?
  Another problem: I already know how to search for a specific user. However, if that user has more than 1 email, if i search for the non-default email, he can't find it! How can I resolve this question using ExchangeService?
  I saw the question <a href="https://stackoverflow.com/questions/2071668/how-to-get-contact-list-from-exchange-server">How to get contact list from Exchange Server?</a> but, by this way, I only can access my own address list (i want all organization address list).</p>
