title: html outlook mso-border-bottom-alt not working
body: <p>Need to underline a text link that has a <sup>®</sup></p>
  <p>The underline for the ® is not lined up with the rest of the words so a border-bottom is used instead. But in Outlook 2016 and 2019, the border-bottom disappears.</p>
  <p>I searched and found this mso-border-bottom-alt that are supposed to work.</p>
  <p>Here is the code:</p>
  <pre><code>.border { 
  mso-border-right-alt: none #FFFFFF 0;
  mso-border-bottom-alt: none #FFFFFF 0;
  mso-border-left-alt: none #FFFFFF 0;
  mso-border-top-alt: solid #903010 2pt; /* px works too */
  }
  </code></pre>
  <p>It only works to add all borders but not just the bottom border.</p>

  <p>Can someone tell me why this is not working?
  Thanks!</p>
