We’ll also take a look at how to spruce things up even further using Outlook Themes.
Step 1. Head to the Settings
Look to the top-right corner of your screen and locate the Settings icon. It looks like a gear.
Click it. A list of settings options will appear.
Step 2. Locate and Toggle Dark Mode
You’ll find Outlook’s Dark mode setting right under the Theme section. While unchecked, it looks like a grey slider. Click it to turn it on.
You’re all set! Enjoy using Outlook in Dark mode.
Outlook Themes
Browsing your inbox doesn’t have to be dull and draining. Outlook Themes are a great way to liven things up (and they can be used with both Light and Dark mode).
Locating a new theme is just as simple as turning on Dark mode. Head to Settings, then right below the Search Outlook settings bar you’ll find the Theme section.
You can choose any of the 10 top options or select the View all button to load a larger list of Outlook themes.
These solid colors, gradients, or illustrations are applied to the Outlook toolbar upon selection. The displayed font color will also change to match your selected theme.
If you decide a new theme isn’t for you, you can always revert to Outlook’s default Organizational theme at any time.
Dark Mode Is Available in All Microsoft Office Apps
If you use other Microsoft Office apps as well as Outlook, you might want to enable Dark mode in those apps too. This way you get a consistent appearance across all your productivity apps: Outlook, Word, Excel, and more.
