  • Thin lines are inserted in emails in Outlook 2016 (or 2019) on Windows. This is a known bug with Outlook 2016's old Microsoft Word based rendering engine.

  • Also in Outlook 2016 running on Windows, not all line heights are working as intended. For example line heights of 1.3 and 1.8 look the same.

  • Background images aren't shown. Read more.

  • Certain fonts won't show up as specified. A fallback font is used. Read more.

  • Animated GIFs will only show the first frame of the animation. Check out this great blog post by Litmus for details.

  • Displaying transparent PNGs doesn't work reliably.
