title: Replying / Forwarding HTML email in Outlook shows hidden content / breaks
body: <p>I'm utilising a technique for producing "responsive" emails which involves having two versions. One explicitly written for desktop and one written for mobile. Using a combination of conditional statements and CSS (mso-hide:all; display:none;) to hide the mobile version when in a desktop client and vice versa. </p>
  
  <p>This works perfectly, and as intended. When I go to forward or reply to one of these emails, the styling breaks and the previously hidden 'mobile' version is shown. I've tried using inline styles (mso-hide:all; display:none;) on the table, as well as applying a class and using conditional comments to apply the same styling in a CSS fashion, but it's not working. </p>
  
  <p>I'd show an example, but the work is rather sensitive. </p>
  
  <p>Basically, I'm after a way to hide a table in Outlook and have it stay hidden when the email is replied to / forwarded. </p>
