title: Powershell-script: Read Contacts from excel file, and create Mailboxes for them on Microsoft Exchange
body: <p>I tried things out and not with much success.
  I don't want to know the whole solution for this problem, but where should I start (or maybe there already exist a solution)?
  Should I better convert the excel file to CSV or XML?
  Or maybe should I put some C# in it ?</p>
  
  <p>Here are some more details:</p>
  
  <ol>
  <li>Attributes that should be readed and then filled in the mailbox: Name, Lastname, Display Name, Alias, e-mail(genrated from name and lastname).</li>
  <li>Checkbox must be unchecked: "Automatically update e-mail adresses based on e-mail adressess policy"</li>
  <li>Generate e-mails from the names with addtional domain (example: Name: Dennis, Lastname: Ritchie, e-mail:Dennis.Ritchie@testdomain.com). </li>
  </ol>
