How to Enable Dark Mode in Outlook for Windows 11
You enable dark mode in Outlook for Windows 11 to switch its interface from a bright white to a dark color scheme, which helps reduce eye strain and can conserve battery life on OLED displays.
Dark mode applies a high-contrast color palette, enhancing readability by making text stand out and reducing overall screen glare, especially in dimly lit environments.
This feature is readily available for Outlook versions that integrate with the Windows 11 dark theme, typically found in current Microsoft 365 subscriptions.
In New Outlook, click the sun/moon icon in the top right to cycle themes or go to Settings > General > Appearance. For Classic Outlook, click File > Office Account and select Black or Dark Gray under Office Theme.

Why is my reading pane still white in dark mode?
Your Outlook reading pane might still look white in dark mode because the email message background needs its own setting changed.
Does changing Outlook to dark mode affect other Office apps?
In the Classic Outlook version, yes. Because it uses the Office 365 account settings, changing the theme to Black or Dark Gray will automatically update Word, Excel, and PowerPoint to match. The New Outlook version is independent and only changes the theme for the email application.
How do I toggle dark mode for a single email only?
You can toggle the background of a single email by clicking the sun or moon icon located in the top right corner of the message reading pane. This allows you to view a specific email in light mode while keeping the rest of your Outlook interface in dark mode.
