Columns not displaying side-by-side in Outlook 2016

[ns-alexmueller]

Hey folks, I'm running into an issue with displaying columns side-by-side in Outlook 2016.

Here's the MJML I've been using:

<mjml owa="desktop">
  <mj-body>
    <mj-section>
      <mj-column>
        <!-- Your first column -->
        <mj-text>column 1</mj-text>
      </mj-column>
      <mj-column>
        <!-- Your second column -->
        <mj-text>column 2</mj-text>
      </mj-column>
    </mj-section>
  </mj-body>
</mjml>

It's basically just the demo MJML from the documentation with some text added and owa set to "desktop".

I expected the columns to be displayed side-by-side, but for some reason, they are always stacked like this:

I'm not sure if this is a bug or if I'm just missing something extremely obvious in the MJML I provided.

Also, I'm using MJML v4.15.3.

How did you send your email ? Can you try with https://putsmail.com/ (without checking inline style)

I think I figured out the issue. We are sending emails using go and parsing the MJML-generated HTML files with the standard html/template library. The library strips out comments from the HTML during parsing, so all of the comments used to support outlook-specific behaviors were being removed. I was able to get around this by wrapping the comments using the method in this stackoverflow post.
