title: AD Account Will Not Create If Duplicate First Name & Second Name
body: <p>I am creating a script to create users on a domain for one of my clients (NHS in the UK), however it currently refuses to create the AD User &amp; exchange account if the user has a First &amp; Second Name that Already Exists within the AD.</p>
  
  <p>I have already bypassed username duplication by adding a number onto the end of the usernames if they already exist. However, if the first / second name is duplicated it will not create the account.</p>
