How to Enable or Disable Dark Mode in Outlook for Windows 11
Dark mode in Outlook for Windows 11 changes the app’s look to a dark color scheme, which helps reduce eye strain, especially when you’re using your computer in dim lighting.
This dark mode feature offers a high-contrast look with a dark background and light text to make reading easier.
You can find this option in Outlook’s appearance settings and turn it on or off easily.
Applying dark mode can even help save battery life on some screens, and it works for both the new and classic versions of Outlook on Windows 11.
In New Outlook, go to Settings > General > Appearance and select your theme. In Classic Outlook, go to File > Office Account and choose a theme under Office Theme. The reading pane also has a sun/moon icon to toggle message backgrounds.
