I'm creating a signature in Outlook for Windows (latest build as I write this) and my signature is not working great in dark mode, so I changed the HTML to use different images if the user is in Dark Mode:
<picture>
<source
srcset="DarkMode_files/image002_dark.png"
media="(prefers-color-scheme: dark)">
<img src="DarkMode_files/image002.png">
</picture>
</div>
This strategy works perfectly in Chrome as I debugged this already. However in Outlook it always uses the non-dark mode ignoring my dark mode settings.
I understand Outlook doesn't support this yet? Thanks for confirming.
