Enabling the dark theme in Outlook changes the entire application window to a darker color scheme. If you are wondering how to make outlook dark theme, you have come to the right place. This guide walks you through every method for Outlook on Windows, Mac, web, and mobile. By the end, your eyes will thank you, especially during late-night email sessions.
Dark mode reduces eye strain and saves battery on OLED screens. It also looks modern and sleek. Microsoft has made this feature available across all versions of Outlook, but the steps vary slightly. Let us break it down for you.
How To Make Outlook Dark Theme
First, we cover the desktop version for Windows. This is the most common setup for office workers and home users alike. The process is straightforward, but you need to know exactly where to click.
For Outlook On Windows (Microsoft 365 And Office 2021)
Open Outlook on your computer. Look at the top-left corner and click on File. This opens the backstage view. From there, select Office Account or Account depending on your version.
Under Office Theme, you will see a dropdown menu. Click it and choose Black. This applies the dark theme to the entire Outlook window, including the ribbon and reading pane. Some users also see Dark Gray as an option, which is a softer alternative.
If you do not see the Black option, your subscription might be outdated. Update Outlook via File > Office Account > Update Options. After updating, restart Outlook and try again.
Alternative Method: Using Personalize Settings
Another way is through Windows Settings. Go to Settings > Personalization > Colors. Under Choose your default app mode, select Dark. This forces many apps, including Outlook, to use dark mode. However, this method is less precise and may not apply to all Outlook elements.
For best results, stick with the Office Theme dropdown inside Outlook itself.
For Outlook On Mac
Mac users have a slightly different process. Open Outlook and click on Outlook in the menu bar at the top of the screen. Then select Preferences.
In the Preferences window, click on General. Look for the Personalize section. Here, you will find an option called Appearance. Choose Dark from the dropdown.
Alternatively, you can use the macOS system-wide dark mode. Go to System Preferences > General and select Dark under Appearance. Outlook will automatically follow this setting if you have not overridden it in the app preferences.
One tip: If you switch between light and dark modes often, use the system setting. It syncs across all your Mac apps, not just Outlook.
For Outlook On The Web (Outlook.com)
The web version of Outlook is popular for personal email. To enable dark theme, log in to outlook.com. Click the gear icon (Settings) in the top-right corner.
Scroll down to the bottom of the Settings pane and click View all Outlook settings. Then go to General > Appearance. Under Theme, select Dark. You can also choose Dark mode from the dropdown if available.
Some users report that the web version only dims the background but not the email content. To fix this, toggle the Dark mode for reading messages option on. This ensures emails appear with a dark background and light text.
For Outlook Mobile (IOS And Android)
Mobile users spend hours on email. Dark mode here is a lifesaver for battery and comfort. On an iPhone or iPad, open the Outlook app. Tap your profile picture or the hamburger menu (three lines) in the top-left.
Scroll down and tap the gear icon for Settings. Then select Mail or General depending on your app version. Look for Appearance or Theme. Choose Dark from the options.
On Android, the steps are nearly identical. Open Outlook, tap your profile icon, go to Settings, and select Theme. Pick Dark. Some Android devices also let you force dark mode system-wide, which Outlook will respect.
If you prefer automatic switching based on time of day, look for the System default option. This uses your phone’s dark mode schedule.
Common Issues And Fixes
Sometimes the dark theme does not apply correctly. Here are the most frequent problems and their solutions.
Dark Theme Not Showing In Outlook
If you selected Black or Dark but nothing changed, try restarting Outlook. A full restart often refreshes the theme. If that fails, check for updates. Go to File > Office Account > Update Options > Update Now.
Another cause is a corrupted cache. Close Outlook, press Windows Key + R, type %localappdata%\Microsoft\Outlook, and delete the RoamCache folder. Restart Outlook and apply the theme again.
Dark Theme Only Applies To Part Of The Window
Some users see a dark ribbon but a white reading pane. This happens when the theme is not fully supported. In Outlook for Windows, ensure you selected Black under Office Theme, not just Windows mode. Also, check if you have the latest version of Office.
For web users, enable the Dark mode for reading messages toggle. This forces email content to display in dark colors.
Dark Theme Resets After Restart
This is rare but annoying. It usually occurs due to Group Policy settings in corporate environments. If you are on a work computer, contact your IT admin. They may have locked the theme. For personal devices, repair Office via Control Panel > Programs > Microsoft Office > Change > Quick Repair.
Benefits Of Using Dark Theme In Outlook
Why bother with this setting? The benefits go beyond aesthetics. Here are the key advantages.
- Reduced eye strain: Staring at a bright screen for hours causes fatigue. Dark mode lowers blue light exposure, making it easier on your eyes.
- Better battery life: On OLED and AMOLED screens, dark pixels consume less power. This extends your device’s battery life significantly.
- Improved focus: A darker interface reduces distractions. Your eyes naturally focus on the content, not the bright background.
- Modern look: Dark theme gives Outlook a clean, professional appearance that many users prefer.
These benefits make the switch worthwhile, especially if you manage multiple email accounts daily.
How To Customize The Dark Theme Further
Once you have the basic dark theme, you can tweak it. Outlook offers limited customization, but here are a few options.
Change Accent Colors
In Outlook for Windows, go to File > Options > General. Under Personalize your copy of Microsoft Office, you can change the Office Theme and Background. The background option adds subtle patterns, but it works with dark mode.
For Mac, go to Outlook > Preferences > General. You can adjust the accent color there, though it is minimal.
Use High Contrast Mode
Windows has a High Contrast setting that overrides Outlook themes. Go to Settings > Ease of Access > High contrast. Turn it on and choose a dark theme. This forces all apps, including Outlook, to use high-contrast dark colors. It is more aggressive but useful for accessibility.
Third-Party Tools
Some users install add-ins like Dark Mode for Outlook from the Office Store. These tools offer deeper customization, such as changing the background of email messages. Be cautious with third-party tools; only download from trusted sources.
Dark Theme For Different Outlook Versions
Not all Outlook versions are the same. Here is a quick reference for older releases.
Outlook 2019 And 2016
These versions support dark theme but with limitations. Go to File > Options > General. Under Personalize your copy of Microsoft Office, choose Black from the Office Theme dropdown. The ribbon and background turn dark, but the reading pane may remain light. This is normal for these versions.
Outlook 2013 And Earlier
Older versions do not have a native dark theme. Your best bet is to use Windows High Contrast mode or upgrade to a newer Office subscription. Microsoft 365 includes the full dark theme experience.
Outlook For Business (Exchange)
If your company uses Exchange, the dark theme works the same as the consumer version. However, IT policies may restrict changes. If you cannot find the option, ask your admin to enable it via Group Policy.
