Although on Windows 10, many apps can match the system color scheme, Microsoft Teams won’t automatically switch to the color scheme when enabling the dark mode.
The reason is that you need to enable dark mode on Teams manually using the app settings.
Enable dark mode on Microsoft Teams
To enable dark mode on Teams, use these steps:
Open Microsoft Teams.
Click on the Settings and more (ellipsis) button from the top-right corner.
Select the Settings option.
Click on General.
Under the “Theme” section, select the Dark option to enable the dark mode on Microsoft Teams.
Once you complete the steps, Microsoft Teams will switch to a dark color scheme. You can also select the “High contrast” option on the same page if you need to use that color scheme.
We’re focusing this guide on Windows 10, but you can switch to the light or dark theme on Teams in other platforms, including macOS and Linux.
