title: imap_list() in PHP not showing me my "Additional Mailbox"
body: <p>I am trying to connect to the inbox of an "Additional Mailbox" on a Microsoft Exchange server. Connecting to my server and running imap_list does NOT show the mailbox, but it is listed using Outlook. I see the rest of my folders though.</p>
  
  <pre><code>$mbox = imap_open( '{mail.domain.net:143}', 'username', 'password' );
  
  echo '&lt;pre&gt;';
  echo "&lt;h1&gt;Mailboxes&lt;/h1&gt;\n";
  $folders = imap_list($mbox, "{mail.domain.net:143}", "*");
  
  if ($folders == false) {
      echo "Call failed&lt;br /&gt;\n";
  } else {
      foreach ($folders as $val) {
          echo $val . "&lt;br /&gt;\n";
      }
  }
  </code></pre>
