title: Select-Object - what can I select?
body: <p>I'm learning PowerShell and I am stuck at an issue where I have to export something and I don't know its object name.</p>
  
  <p>I use this command:</p>
  
  <pre><code>Get-Mailbox -ResultSize Unlimited | Select-Object DisplayName,PrimarySmtpAddress
  </code></pre>
  
  <p>How do I find out what objects I can select with <code>Select-Object</code>?</p>
