title: How to access shared mailbox's Contacts Address Book in Outlook programmatically
body: <p>I have four mailboxes in my Outlook 2013 client at work, my personal (Me@MyCompany.Com) and the other three are shared mailboxes for projects/teams I am on, for example, (Sales@MyCompany.Com), (ProjectFinance@MyCompany.Com), etc. </p>
  
  <p>I am using C# and can access the Contacts Address Book for my own mailbox just fine, but I would like to know how to access another mailbox's Contacts?</p>
  
  <p>This works fine when accessing my own Contacts:</p>
  
  <pre><code>Outlook.MAPIFolder myContactsFolder = application.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
  </code></pre>
  
  <p>What is the equivalent for say mailbox (Sales@MyCompany.Com)?  I do have the username and password for this account just in case you need it but I don't believe you need it since I am creating an AddIn that will be used during the user's active session.</p>
