How to Enable Dark Mode in Outlook

If you are a dark mode fan and are using Microsoft Office applications, enabling system-wide dark mode in Windows 10 will have no impact on the Office apps. The Microsoft 365 apps come with their own dark mode (black and grey) themes that can be activated for each Office app individually. You can also enable dark mode on Outlook.com.

Let us show you how you can enable the dark theme on your Outlook, both on the web as well as within the standalone app. Note that the Outlook standalone version that comes with Office 365 supports the dark theme, whereas Outlook 2013 and 2016 currently do not support this feature.

Enable dark mode in Microsoft Outlook app

To open Outlook in dark mode, click File in the top-left corner of the app and then click Office account. Now open the drop-down menu below Office theme and select Black.

Moreover, you can switch the background color of your email from light to dark by‌ ‌clicking‌ ‌the‌ ‌”moon”‌ ‌or‌ ‌the‌ ‌”sun”‌ ‌icon‌ ‌from‌ ‌the‌ ‌top‌ ‌menu‌ ‌bar.

Enable dark mode in Outlook.com web

The online version of Outlook.com is an email client that can be accessed using any browser provided that they‌ ‌have‌ ‌an‌ ‌active‌ ‌internet‌ ‌connection. Here is how you can set a dark theme for Outlook Web.

Closing words

Having the option to switch between dark and light themes is always a good idea, regardless of whether you use them. With these quick-change buttons, you can now easily and swiftly switch from one mode to another depending on the time of day and your personal preference.

Hopefully, the Microsoft 365 apps will also follow the Windows 10 system-wide light or dark mode, making it easier for users to use dark mode or light mode across all system apps.
