title: Replace a null value with string in multple field
body: <p>how can I replace a $null value in the <code>Lastlogon</code> field by a string "never log" and also place this value in the column "Last Logon days"</p>
  
  <pre><code>Search-ADAccount -UsersOnly  -AccountDisabled:$false | Get-ADUser -Properties Name, LastLogon | select Name, @{N='LastLogon'; E={[DateTime]::FromFileTime($_.LastLogon)}}, @{N='Last Logon Days'; E={$($(Get-Date) - $([DateTime]::FromFileTime($_.LastLogon))).Days}}
  </code></pre>
  
  <p>I have accounts that never logged on the network and they are returning a last logon date of 12/31/1600 7:00:00 PM  which is a bite far away. </p>
