by

Switching Outlook’s dark mode off returns the interface to a familiar, high-contrast white background. If you have been wondering how to turn off dark mode on outlook, you are not alone—many users find the dark theme harder to read in bright environments or simply prefer the classic look. This guide will walk you through every method for disabling dark mode across Outlook desktop, web, and mobile apps, with clear steps and troubleshooting tips.

Understanding Dark Mode In Outlook

Dark mode changes the background of Outlook from white to dark gray or black, with light text. It is designed to reduce eye strain in low-light settings. However, it can make reading emails or navigating menus difficult for some users. Microsoft offers several ways to toggle this setting, depending on your version of Outlook.

Before you start, check which Outlook version you use. The steps differ slightly between Outlook 365, Outlook 2019, Outlook on the web, and the mobile app. We will cover all major platforms so you can find the exact solution for your setup.

How To Turn Off Dark Mode On Outlook

This section provides the core instructions for disabling dark mode. Follow the steps that match your Outlook version.

Turning Off Dark Mode In Outlook Desktop (Windows)

For Outlook 365 or Outlook 2019 on Windows, the setting is located in the Office Theme options. Here is how to change it:

  1. Open Outlook on your Windows computer.
  2. Click on File in the top-left corner of the ribbon.
  3. Select Options from the left sidebar. A new window will open.
  4. In the Outlook Options window, go to the General tab.
  5. Under the “Personalize your copy of Microsoft Office” section, find the Office Theme dropdown menu.
  6. Click the dropdown and choose White or Colorful. Avoid selecting “Black” or “Dark Gray.”
  7. Click OK to save the changes. The interface should immediately switch to a light background.

If the dark mode persists, restart Outlook. Sometimes the theme does not apply until you close and reopen the program.

Disabling Dark Mode In Outlook For Mac

Mac users have a slightly different process. Outlook for Mac syncs with your system-wide appearance settings. To turn off dark mode:

  1. Open Outlook on your Mac.
  2. Click on Outlook in the menu bar at the top of the screen.
  3. Select Preferences from the dropdown.
  4. In the Preferences window, click on General.
  5. Look for the Appearance section. You will see options like “Light,” “Dark,” and “System.”
  6. Choose Light to force a white background. If you select “System,” Outlook will follow your Mac’s dark mode setting, which may keep it dark.
  7. Close the Preferences window. The change takes effect immediately.

Note: On newer MacOS versions, Outlook may also respect the system-wide dark mode toggle in System Settings. If the above does not work, check your Mac’s Display settings and set Appearance to “Light.”

Turning Off Dark Mode In Outlook On The Web

Outlook on the web (OWA) has its own theme settings. To disable dark mode in your browser:

  1. Go to outlook.live.com or your work’s Outlook web portal.
  2. Sign in with your email account.
  3. Click the Settings gear icon (cogwheel) in the top-right corner.
  4. At the bottom of the Settings pane, click View all Outlook settings.
  5. In the Settings window, navigate to General > Appearance.
  6. Under “Theme,” you will see a dropdown or a toggle for dark mode. Select Light or Use system setting (if you want it to match your browser).
  7. Click Save at the top. The page will refresh with the light theme.

If you use Outlook.com (personal account), the steps are similar. The dark mode toggle may appear directly in the Settings pane without needing to click “View all Outlook settings.”

Disabling Dark Mode In Outlook Mobile (IOS And Android)

The Outlook mobile app allows you to switch themes independently of your phone’s settings. Here is how to turn off dark mode:

  • On iPhone/iPad: Open the Outlook app. Tap your profile picture or the hamburger menu (three lines) in the top-left corner. Scroll down and tap the gear icon for Settings. Under “Mail,” tap Appearance. Select Light to disable dark mode. You can also choose “System” to follow your device’s setting.
  • On Android: Open the Outlook app. Tap your profile picture in the top-left corner. Tap the gear icon to open Settings. Under “Mail,” tap Theme. Choose Light from the options. The change applies instantly.

If your phone is in dark mode and you set Outlook to “System,” it will remain dark. Always select “Light” to override this.

Common Issues When Disabling Dark Mode

Sometimes the steps above do not work as expected. Here are frequent problems and their fixes.

Dark Mode Still Shows After Changing Theme

If you selected “White” or “Light” but Outlook remains dark, try these solutions:

  • Restart Outlook completely. Close the app and reopen it.
  • Check if your Windows or Mac system is in dark mode. Outlook may inherit the system theme. Go to your computer’s display settings and set it to light mode temporarily.
  • Update Outlook to the latest version. Older versions may have bugs that prevent theme changes.
  • Clear your Outlook cache. On Windows, close Outlook, then delete files in %localappdata%\Microsoft\Outlook\RoamCache. Restart Outlook.

Reading Pane Or Email Body Still Dark

In some versions, the reading pane may stay dark even after the main interface changes. This is often a separate setting:

  • In Outlook desktop, go to File > Options > Mail. Under “Stationery and Fonts,” click Stationery and Fonts. In the “Personal Stationery” tab, under “Theme or stationery for new mail messages,” choose a light theme like “Blank.”
  • For the reading pane, check View > View Settings > Conditional Formatting. Remove any dark formatting rules that may apply to emails.
  • On Outlook web, ensure you have not set a custom dark theme for individual emails. The “Use dark mode for messages” toggle in Settings > General > Appearance should be off.

Dark Mode Reverts After Update

Microsoft updates sometimes reset theme preferences. If dark mode returns after an update, simply repeat the steps above. To prevent this, you can also set your system-wide theme to light, as Outlook may follow it.

Why You Might Want To Keep Dark Mode Off

Many users prefer the light interface for several reasons:

  • Better readability in bright environments, such as offices or outdoors.
  • Easier to distinguish between different sections of the interface.
  • Reduced eye strain for some people, especially when reading long emails.
  • Consistency with other Office apps that use a light theme.
  • Familiarity with the classic Outlook layout.

However, dark mode can be beneficial for low-light use. You can always toggle it back on later if needed.

Additional Tips For Managing Outlook Appearance

Beyond dark mode, you can customize Outlook’s look further:

  • Change the accent color: In Outlook desktop, go to File > Options > General. Under “Personalize your copy of Microsoft Office,” choose a different Office Theme color (e.g., Blue, Green, or Pink).
  • Adjust the reading pane background: In Outlook web, go to Settings > General > Appearance and select a custom background color for emails.
  • Use high contrast mode: If you need better visibility, enable Windows High Contrast mode (Settings > Ease of Access > High contrast). Outlook will adapt.
  • Reset to default settings: If you have made many changes and want a clean slate, go to File > Options > Advanced and click “Reset” under “Other.” This restores default view settings.

Frequently Asked Questions

How do I turn off dark mode in Outlook 365?

For Outlook 365 on Windows, go to File > Options > General and set Office Theme to “White” or “Colorful.” On Mac, use Outlook > Preferences > General and select “Light” under Appearance.

Can I disable dark mode only for reading emails?

Yes, in Outlook web, you can turn off “Use dark mode for messages” in Settings > General > Appearance. In desktop, you may need to change the stationery theme to a light one.

Why does my Outlook keep switching back to dark mode?

This often happens because Outlook syncs with your system theme. Set your computer’s display to light mode, or choose “Light” explicitly in Outlook’s settings instead of “System.”

Does turning off dark mode affect how emails look?

No, disabling dark mode only changes the interface background. Email content remains unchanged, though some users notice that dark mode can invert colors in images or signatures.

Is there a keyboard shortcut to toggle dark mode in Outlook?

No direct shortcut exists. You must use the settings menu. However, on Windows, you can press Alt+F, T, G to quickly open the General tab in Options.

Final Thoughts On Managing Outlook’s Theme

Knowing how to turn off dark mode on outlook gives you control over your workspace. Whether you prefer the classic white background for clarity or need to match your company’s branding, the steps in this guide cover all major platforms. If you encounter persistent issues, check for updates or reset your settings.

Remember that Outlook’s theme is separate from your email account settings. Changing the theme does not affect your emails, folders, or rules. It is purely a visual preference. Feel free to experiment with different themes until you find the one that works best for you.

If you switch between devices, you may need to disable dark mode on each one individually. Outlook does not sync theme settings across platforms. For a consistent experience, set all your devices to light mode.
