title: Get address of group of users from Exchange 2010 via web services SDK
body: <p>We would like to display a list of address. We are trying to design a system where the addresses are only stored in one place, that place being Exchange 2010.</p>
  
  <p>Is there a web service in the Exchange 2010 SDK, that allows us to get the names and address of all users in a group?</p>
  
  <p>Is there a better way to do this, for example getting the data from AD?</p>
