How To Turn Off Outlook Dark Mode – Dark Mode Outlook Disable Steps

by

Outlook’s dark theme is stylish, but reverting to a light color scheme can reduce eye strain in bright rooms. If you’re wondering how to turn off outlook dark mode, you’ve come to the right place. This guide covers every version of Outlook, from desktop to web and mobile, with clear steps and screenshots-like instructions. Whether you accidentally enabled dark mode or just prefer a brighter interface, we’ll show you exactly what to do.

Dark mode in Outlook can be a great feature for late-night email checking, but it’s not for everyone. In well-lit offices or sunny environments, the dark background can actually make text harder to read. That’s why knowing how to switch back is essential for many users.

Below, you’ll find step-by-step instructions for Outlook 365, Outlook 2019, Outlook 2016, Outlook on the web, and the Outlook mobile app. We’ll also cover common troubleshooting issues and answer frequently asked questions.

How To Turn Off Outlook Dark Mode

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

Turning Off Dark Mode In Outlook 365 And Outlook 2019

Outlook 365 and 2019 share a similar interface. The dark mode setting is located in the general options menu.

  1. Open Outlook and click on File in the top-left corner.
  2. Select Options from the left-hand menu.
  3. In the Outlook Options window, click on General.
  4. Look for the “Personalize your copy of Microsoft Office” section.
  5. Find the Office Theme dropdown menu.
  6. Click the dropdown and select White or Colorful (not Dark Gray or Black).
  7. Click OK to apply the changes.

That’s it. Outlook will immediately switch to a light color scheme. If you selected “White,” the entire interface will be bright. “Colorful” adds a touch of blue accents while staying light.

What If The Office Theme Doesn’t Change Everything?

Sometimes, even after changing the Office Theme, the reading pane or message list remains dark. This is because Outlook 365 has a separate setting for message background. To fix this:

  1. Go to File > Options > Mail.
  2. Scroll down to the “Message format” section.
  3. Uncheck the box that says “Use dark mode for messages” or similar wording.
  4. Click OK.

This ensures both the interface and individual emails appear in light mode.

Turning Off Dark Mode In Outlook 2016 And Earlier

Outlook 2016 and older versions have a slightly different menu structure. The dark mode option is still there, but it’s called “Dark Gray” theme.

  1. Open Outlook and click File > Options.
  2. Select General from the left pane.
  3. Under “Personalize your copy of Microsoft Office,” find the Office Theme dropdown.
  4. Choose White or Light Gray.
  5. Click OK.

In Outlook 2016, there is no separate message dark mode toggle. Changing the Office Theme should revert everything to light mode.

Turning Off Dark Mode In Outlook On The Web (OWA)

Outlook on the web (outlook.com or your work webmail) also has a dark mode option. It’s easy to disable.

  1. Log in to your Outlook web account.
  2. Click the gear icon (Settings) in the top-right corner.
  3. Scroll down and click View all Outlook settings at the bottom.
  4. In the Settings panel, go to General > Appearance.
  5. Under “Theme,” select Light instead of Dark.
  6. Click Save.

The web version will refresh instantly. If you don’t see the Appearance option, your organization may have disabled theme changes. Contact your IT admin in that case.

Turning Off Dark Mode In The Outlook Mobile App (IOS And Android)

The Outlook mobile app follows your device’s system settings by default, but you can override it.

For iOS (iPhone/iPad):

  1. Open the Outlook app.
  2. Tap your profile picture or initials in the top-left corner.
  3. Tap the gear icon (Settings) at the bottom.
  4. Select Appearance.
  5. Choose Light or System (if you want it to follow your phone’s settings).
  6. Tap Save.

For Android:

  1. Open Outlook and tap your profile picture in the top-left.
  2. Tap the gear icon (Settings).
  3. Select Appearance.
  4. Choose Light or System default.
  5. Tap Done.

On both platforms, the change is immediate. If you choose “System,” Outlook will match your phone’s dark mode setting. To keep it light permanently, select “Light.”

Why Is Outlook Still Dark After Changing Settings?

Sometimes the dark mode setting doesn’t stick. Here are common reasons and fixes:

  • Multiple themes active: Outlook 365 has both Office Theme and a separate dark mode for messages. Make sure you change both.
  • Windows dark mode override: If Windows is in dark mode, some Office apps may follow that. Go to Windows Settings > Personalization > Colors and set “Choose your default app mode” to Light.
  • Add-in interference: Third-party add-ins can force dark mode. Try disabling add-ins one by one via File > Options > Add-ins.
  • Corrupted profile: A damaged Outlook profile may ignore theme settings. Create a new profile via Control Panel > Mail > Show Profiles.
  • Group policy restriction: In corporate environments, IT may enforce dark mode. Contact your help desk.

How To Disable Dark Mode For Specific Folders Or Emails

You might want to keep the overall interface light but have dark mode for certain folders. Unfortunately, Outlook doesn’t support per-folder theming. However, you can use conditional formatting to change the appearance of emails in specific folders. This doesn’t change the background color, but it can help readability.

  1. Go to View > View Settings.
  2. Click Conditional Formatting.
  3. Create a new rule and set conditions for the folder.
  4. Choose font color and style.

This is a workaround, not a true dark mode toggle for individual folders.

Keyboard Shortcuts For Quick Theme Switching

There’s no direct keyboard shortcut to toggle dark mode in Outlook. But you can create a macro to switch themes quickly. Here’s a simple VBA macro:

  1. Press Alt + F11 to open the VBA editor.
  2. Go to Insert > Module.
  3. Paste the following code:
Sub ToggleTheme()
    If Application.Theme = "Dark" Then
        Application.Theme = "White"
    Else
        Application.Theme = "Dark"
    End If
End Sub
  1. Close the editor and assign the macro to a button or keyboard shortcut via File > Options > Customize Ribbon.

This macro toggles between dark and light themes. Note that it may not work in all versions.

How To Turn Off Dark Mode In Outlook For Mac

Outlook for Mac has its own dark mode setting, separate from the Windows version.

  1. Open Outlook on your Mac.
  2. Click Outlook in the top menu bar.
  3. Select Preferences.
  4. Click General.
  5. Under “Appearance,” choose Light or System.
  6. Close the Preferences window.

If you choose “System,” Outlook will follow your Mac’s dark mode setting. To keep it light permanently, select “Light.”

Common Mistakes When Turning Off Dark Mode

Many users accidentally enable dark mode again without realizing it. Here are common pitfalls:

  • Clicking “Dark” in the theme dropdown by mistake: Double-check your selection before clicking OK.
  • Using a Windows high-contrast theme: This can override Outlook’s settings. Go to Windows Ease of Access > High contrast and turn it off.
  • Syncing settings across devices: If you have multiple devices, changing the theme on one may sync to others. Turn off sync if needed.
  • Third-party dark mode extensions: Browser extensions can force dark mode on Outlook web. Disable them temporarily.

How To Keep Outlook In Light Mode Permanently

To ensure Outlook stays light even after updates or reboots, follow these tips:

  • Set both Office Theme and message dark mode to Light/White.
  • Disable Windows dark mode for apps.
  • Turn off automatic theme switching in Outlook (if available).
  • Export your theme settings via File > Options > General > Export settings.
  • Keep Outlook updated to avoid bugs that reset themes.
