title: Add proxyAddresses to Active Directory users when created in PowerShell
body: <p>I am trying to add users in Active Directory. Those users need to have proxyAddresses. My problem is that those proxyAddresses are multiples and stored in an array.</p>
  
  <p>I try :</p>
  
  <pre><code>$proxyAddresses = @("address1@test.com", "address2@test.com", "address3@test.com")
  $userInstance = new-object Microsoft.ActiveDirectory.Management.ADUser
  $userInstance.ProxyAddresses = $proxyAddresses
  New-ADUser test -Instance $userInstance
  </code></pre>
  
  <p>And I get this error :</p>
  
  <pre><code> Invalid type 'System.Management.Automation.PSObject'. Parameter name: proxyAddresses
  </code></pre>
  
  <p>I would like to add this proxyAddresses array to the attribute proxyAddresses of my AD user but it don't seem to be possible.</p>
  
  <p>Any idea how this could be done?</p>
