As of this week, Windows 10 Mail finally has a Dark Mode worth using. After a few weeks of testing, the upgraded Mail and Calendar app now includes a more useful version of the feature for the email side of the app: one that actually makes the whole app dark, and offers the ability to quickly go “bright” when it’s tough to read.
Technically, the Windows 10 Mail App had a Dark Mode option prior to this update, but the switch only applied to its side menus. The email “reading pane,” where you read and compose emails, remained bright. But no longer! Now, Dark Mode changes all the panels to dark shades of grey, making them easier on the eyes in low light.
To switch to dark mode, click the gear icon near the lower left corner of the app to access the setting menu, then go to “personalisation.” In the Personalisation menu click on “Dark Mode.”
Once it’s on, you can also quickly switch it on and off for the email body using a quick toggle in the toolbar at the top of the window. In Dark Mode, the icon looks like a sun. In light mode, it looks like a moon. As The Verge pointed out, some aspects of an email may be harder to read in Dark Mode, so this is a quick way to make sure you’re able to read the full message.
