title: Last logon mailbox status in Exchange
body: <p>I run the command Get-MailboxStatistics in Exchange Management Shell to check last logon time of users.</p>
  
  <p>Here is command :</p>
  
  <pre><code>Get-MailboxStatistics -Identity username.ou 
  </code></pre>
  
  <p>So for user no 1, powershell return warning something like this :</p>
  
  <blockquote>
    <p>The User Hasn’t Logged on to Mailbox So There is No Data to Return</p>
  </blockquote>
  
  <p>So I guess this user never login to Exchange Mailbox</p>
  
  <p>Then for user no 2, no warning is appear and I got the result but the LastLogonTime is NULL. </p>
  
  <p>So I little bit confuse. What the different the user no 1 and 2? Can someone explain to me due I new in Exchange.</p>
