title: exchange powershell : get-mailbox outside default scope
body: <p>how do you run the cmdlet "get-mailbox" outside the current default scope of the current domain?</p>
  
  <p>When I run get-mailbox -OrganizationalUnit bob.com/bobsage
  I get an error message saying:
  Get-mailbox: The requested search root 'rss.com/rsstoilet' is not in the current default scope 'ens.com'. Cannot perform searches outside the current default scope.</p>
  
  <p>thanks in advance </p>
