How to Change to Dark Mode in Outlook: A Comprehensive Guide

Dark mode, once a niche preference, has blossomed into a mainstream necessity. It’s gentler on the eyes, saves battery life on OLED screens, and, let’s be honest, just looks incredibly sleek. If you’re an Outlook user yearning for the comforting embrace of a darkened interface, you’ve come to the right place. Changing to dark mode in Outlook is generally a straightforward process, but the precise steps can vary slightly depending on the Outlook version you’re using (desktop app, web version, or mobile app) and your operating system (Windows or macOS). Let’s dive into the specifics.

Enabling Dark Mode in Outlook: The Definitive Guide

The primary method to toggle dark mode on or off is within the Outlook settings or options panel. The specific wording might differ subtly across Outlook versions, but the underlying principle remains consistent.

Outlook Desktop App (Windows & macOS)

This section covers the desktop application for both Windows and Mac operating systems.

Open Outlook: Launch the Outlook application on your computer.
Navigate to File: In the upper left corner, click on the “File” tab.
Select Options: In the left-hand menu, usually at the bottom, click “Options.” This will open the Outlook Options dialog box.
Choose General: In the Outlook Options dialog box, select “General” from the left-hand menu.
Personalize Your Copy of Microsoft Office: Look for a section labeled “Personalize your copy of Microsoft Office.” This section typically contains options related to themes and personalization.
Office Theme: Under “Office Theme,” you’ll find a dropdown menu. Click on this menu and select “Black” or “Dark Gray.” The “Black” theme provides the most aggressive dark mode, while “Dark Gray” offers a slightly lighter alternative.
Apply the Changes: Click “OK” at the bottom of the Outlook Options dialog box. The Outlook interface will immediately switch to dark mode based on your selected theme.

Important Note: If you’re using Windows 10 or 11, Outlook might automatically follow your system-wide theme setting. To control Outlook’s theme independently, you can disable this synchronization in Windows settings. Go to Settings > Personalization > Colors and under “Choose your default app mode,” select “Dark” or “Light” to control the system-wide default. If you choose “Custom” and select “Light” for the default app mode and “Dark” for the Windows mode, you can then set a theme in Outlook that overrides the system-level app setting.

Outlook Web Version (Outlook.com & Outlook Web App)

Accessing Outlook through a web browser involves a different set of steps.

Open Outlook in Your Browser: Go to Outlook.com or your organization’s Outlook Web App URL.
Sign In: Log in to your Outlook account using your username and password.
Access Settings: Look for the Settings icon (usually a gear or cogwheel icon) in the upper right corner of the Outlook window. Click on it.
General Settings: A pane will appear on the right side of the screen. At the bottom of the pane, click on “View all Outlook settings“.
General > Appearance: In the Settings window, navigate to “General” and then “Appearance“.
Dark Mode Toggle: You will find a toggle switch labeled “Dark mode.” Toggle this switch to the “On” position to enable dark mode.
Optional Theme Customization: In the Appearance section, you may also find options to customize the theme further, such as adjusting the color of accents or headers.
Close Settings: The changes are usually applied automatically. Simply close the Settings window.

Outlook Mobile App (iOS & Android)

The process for enabling dark mode on the Outlook mobile app is similarly intuitive.

Open the Outlook App: Launch the Outlook app on your iOS or Android device.
Access Settings: Tap on your profile icon in the upper left corner of the screen. This will open a side menu.
Settings Icon: At the bottom left of the side menu, select the Settings (Gear) Icon.
Appearance: Scroll down and tap on “Appearance“.
Theme Options: You’ll see options like “Light,” “Dark,” and “Use System Theme.”
- Light: Forces the app to use light mode.
- Dark: Enables dark mode within the Outlook app.
- Use System Theme: The app will automatically switch between light and dark mode based on your device’s system-wide theme settings.
Select Dark: Choose “Dark” to enable dark mode. If you choose “Use System Theme,” Outlook will follow your phone’s overall theme settings.

Frequently Asked Questions (FAQs)

Here are 12 frequently asked questions about using dark mode in Outlook.

1. Does dark mode in Outlook save battery life?

Yes, especially on devices with OLED screens. OLED screens only illuminate the pixels that are needed, so displaying a dark interface consumes significantly less power compared to a light one. LCD screens, on the other hand, use a backlight that is always on, so the difference is less pronounced.

2. Can I schedule dark mode to turn on and off automatically?

While Outlook itself doesn’t have a built-in scheduling feature for dark mode, you can use your operating system’s built-in scheduling features if you choose to have Outlook follow the system theme settings. For example, Windows 10 and 11 allow you to schedule when the system switches between light and dark mode.

3. Does dark mode affect the formatting of emails I send?

No. Dark mode only changes the appearance of the Outlook interface and the emails you receive. The formatting of the emails you send remains unaffected and will appear as intended to the recipient, regardless of their own Outlook or system settings.

4. Why isn’t dark mode available in my Outlook version?

Dark mode is a relatively recent feature. If you’re using an older version of Outlook, you might need to update to the latest version to gain access to it.

5. My emails still appear with a white background in dark mode. How can I fix this?

This is often related to the email’s formatting. Some senders might use specific HTML formatting that overrides the dark mode setting. There’s not much you can do about this from your end except possibly adjust your Reading Pane settings or use a reader view if your browser supports it. Some email clients offer options to force dark mode on all emails, but Outlook itself doesn’t have this feature.

6. Can I disable dark mode for specific emails?

No, Outlook does not offer a feature to disable dark mode for individual emails. It’s an all-or-nothing setting for the entire application.

7. Does dark mode affect the calendar view in Outlook?

Yes, enabling dark mode will also apply to the calendar view in Outlook, providing a darker background and adjusted text colors.

8. I’m using multiple Outlook accounts. Will dark mode apply to all of them?

In the desktop app, the theme settings are global to the application and will affect all accounts configured within that instance of Outlook. In the web version, dark mode is typically tied to your Microsoft account and will apply across different instances of Outlook Web App that you access using the same account.

9. Is there a performance impact when using dark mode?

Generally, the performance impact of using dark mode is negligible. In some cases, it might even improve performance slightly due to reduced power consumption.

10. Can I customize the colors used in dark mode?

The level of customization is limited. You can typically choose between a “Black” theme and a “Dark Gray” theme. Some versions of Outlook might offer slightly more granular control over accent colors.

11. Dark mode looks different on my phone compared to my computer. Why?

This can be due to differences in the display technology and color calibration of your devices. Additionally, the mobile app might use a slightly different implementation of dark mode compared to the desktop version.

12. Will dark mode be enabled if I upgrade Outlook?

If you previously had dark mode enabled, it should remain enabled after an upgrade. However, it’s always a good idea to verify your settings after any major update to ensure that your preferences are still applied correctly.

By following these instructions and addressing these frequently asked questions, you should have a solid understanding of how to enable and manage dark mode in Outlook across various platforms. Enjoy the comfort and visual appeal of a darkened interface!
