Switching Microsoft Outlook to dark mode reduces eye strain during late-night work sessions. If you have ever wondered how to put microsoft outlook in dark mode, this guide walks you through every method step by step. Whether you use Outlook on Windows, Mac, or the web, you will find clear instructions below.
Dark mode is not just about looks. It helps you focus better in low light and can save battery on OLED screens. Let us get started with the most common versions of Outlook.
How To Put Microsoft Outlook In Dark Mode On Windows
Outlook for Windows offers a built-in dark theme. This setting applies to the entire Office suite if you choose the system option. Follow these steps to enable it.
Step 1: Open Outlook And Go To File
Launch Microsoft Outlook on your Windows computer. Click the File tab in the top-left corner. This opens the backstage view where account and settings options live.
Step 2: Select Office Account
In the File menu, look for Office Account near the bottom of the left sidebar. Click it. You will see your account info and theme options on the right.
Step 3: Choose The Dark Theme
Under Office Theme, click the dropdown menu. Select Black or Dark Gray depending on your preference. The Black theme is true dark mode, while Dark Gray is slightly softer.
Thats it. Outlook will switch to dark mode immediately. If you want the reading pane to also be dark, you need an additional step.
Step 4: Enable Dark Mode For The Reading Pane
Outlooks dark mode sometimes leaves the email reading area white. To fix this, go to View tab and click View Settings. Then choose Conditional Formatting. Look for an option called Dark Mode or Use Dark Mode for Reading. If you do not see it, you may need to update Outlook.
On older versions, the reading pane stays light. You can manually switch to a dark email by clicking Message tab and selecting Dark Mode for individual emails. This is not ideal, but it works.
How To Put Microsoft Outlook In Dark Mode On Mac
Mac users have a slightly different process. Outlook for Mac syncs with your system appearance settings. Here is how to force dark mode.
Step 1: Open Outlook Preferences
Launch Outlook on your Mac. Click Outlook in the top menu bar, then select Preferences. This opens a new window with various settings.
Step 2: Go To General Settings
In the Preferences window, click the General icon. Look for the Personalize section. You will see a dropdown labeled Appearance.
Step 3: Select Dark Mode
Click the Appearance dropdown and choose Dark. If you want Outlook to follow your Macs system setting, select System instead. This will switch Outlook to dark mode automatically when your Mac enters dark mode.
One note: Outlook for Mac does not always darken the email body. You may see a white background when reading messages. To work around this, you can use the Dark Mode button in the email toolbar. Click it to invert colors on the fly.
How To Put Microsoft Outlook In Dark Mode On The Web
Outlook on the web (outlook.com or Office 365) has its own dark mode toggle. This version is popular for quick access without installing software.
Step 1: Sign In To Outlook Web
Go to outlook.com or your Office 365 portal. Sign in with your Microsoft account. The interface will load in light mode by default.
Step 2: Open Settings
Click the gear icon in the top-right corner. This opens the Settings pane. Scroll down and click View all Outlook settings at the bottom.
Step 3: Navigate To General
In the Settings window, click General on the left. Then select Appearance. You will see options for theme and layout.
Step 4: Choose Dark Mode
Under Theme, select Dark. The page will refresh instantly. Your inbox, reading pane, and navigation will all turn dark.
If you prefer a softer look, you can also choose Dark Gray from the same menu. The web version applies dark mode to everything, including email bodies, which is a big advantage over the desktop apps.
How To Put Microsoft Outlook In Dark Mode On Mobile
Outlook mobile apps for iOS and Android support dark mode too. The process is simple and consistent across both platforms.
Step 1: Open The Outlook App
Launch the Microsoft Outlook app on your phone. Tap your profile picture or the menu icon in the top-left corner.
Step 3: Go To Settings
Scroll down and tap the Settings gear icon. This opens the app settings menu.
Step 3: Find The Theme Option
Look for Theme or Appearance. Tap it. You will see three choices: Light, Dark, and System Default.
Step 4: Select Dark
Choose Dark to enable dark mode permanently. If you select System Default, Outlook will match your phones dark mode setting. This is handy if you switch between light and dark modes throughout the day.
On Android, you may also find a Battery Saver option that triggers dark mode automatically. This is a nice extra for saving power.
Troubleshooting Common Dark Mode Issues
Sometimes dark mode does not work as expected. Here are fixes for the most common problems.
Outlook Dark Mode Not Applying To All Elements
If the menu is dark but emails stay white, you need to update Outlook. Microsoft has improved dark mode in recent versions. Go to File > Office Account > Update Options and install any pending updates.
For the web version, clear your browser cache. Outdated cache files can prevent the dark theme from loading correctly.
Dark Mode Making Text Hard To Read
Some users find dark mode text too bright or blurry. Adjust your display brightness or enable High Contrast mode in Windows settings. In Outlook, you can also change the font color manually for better readability.
Dark Mode Not Available In Older Versions
Outlook 2016 and earlier do not support dark mode natively. If you cannot upgrade, consider using a third-party tool like WindowBlinds or Dark Reader browser extension for Outlook web.
Another workaround is to switch to the Microsoft 365 subscription, which includes the latest dark mode features.
Benefits Of Using Dark Mode In Outlook
Dark mode is more than a cosmetic change. Here are real benefits you will notice.
- Reduced eye strain: Dark backgrounds emit less blue light, which is harsh on eyes during long sessions.
- Better focus: Less visual clutter helps you concentrate on emails and tasks.
- Battery savings: On OLED and AMOLED screens, dark pixels consume less power.
- Improved readability: White text on dark background can be easier to read for some people, especially those with light sensitivity.

These benefits make dark mode a smart choice for anyone who spends hours in Outlook daily.
How To Switch Back To Light Mode
If dark mode does not suit you, reverting is easy. Follow the same steps you used to enable it, but choose Light or White instead. On Windows, select Colorful from the Office Theme dropdown to restore the default look.
On Mac, change the Appearance setting back to Light. For the web, select Light under Theme. Mobile users can tap Light in the Theme menu.
You can also toggle between modes quickly by using keyboard shortcuts. On Windows, press Alt + F, T to open Outlook Options, then navigate to General and change the theme. This is faster than clicking through menus.
