How To Revert to Classic Outlook on Windows 11 (and Block the New Outlook)

Microsoft seems to be on a mission to replace traditional Windows programs with web-based applications. A prime example of this is the automatic migration of users from the familiar classic Outlook to the new web-based Outlook Progressive Web App (PWA). For many, even the switch within the web-based Outlook app that once allowed a quick return to the old version has disappeared. If you, like many others, prefer the classic Outlook experience, this guide will show you how to download the classic Outlook on Windows 11 and, more importantly, how to prevent the system from forcing you onto the new web-based version.

Why People Prefer Classic Outlook (and Why Microsoft is Changing Things)

Understanding the Shift: Why Classic Outlook Still Matters

Before we get into the “how-to,” let’s address the elephant in the room: why are people so attached to the classic Outlook, and why is Microsoft pushing for this change? Understanding the reasoning behind both perspectives will give you a better context for the steps we’re about to take.

The classic Outlook, also called the “native Outlook App”, has been a staple of Windows for many years. Millions have grown accustomed to its layout, features, and overall feel. But familiarity goes deeper than just habit. Many specific reasons contribute to users sticking with classic Outlook, even when Microsoft nudges them towards the new PWA version.

The Appeal of Classic Outlook

• Familiarity & Comfort: This is a big one. For many, Outlook is a tool used daily for hours at a time. The classic Outlook’s interface is muscle memory, and everything is where you expect it to be. Learning a new interface, even if it’s “modern,” can cause frustration and loss of productivity. Imagine suddenly changing the layout of your workshop or the controls of your favorite vehicle – it would be jarring and slow you down.
• Offline Access: While the web-based Outlook aims to replicate offline functionality, the classic version often provides a more robust and reliable offline experience. This is crucial for those who travel frequently or work in areas with unreliable internet connections. With the classic version, you can read, compose, and manage emails even without an active internet connection, and changes will sync when you’re back online. The new version has potential limitations if your internet connection is lost.
• Specific Features & Add-ins: Over the years, a vast ecosystem of add-ins and extensions has developed for the classic Outlook. These add-ins provide everything from advanced email management and CRM integration to specialized productivity tools. While the new Outlook supports some add-ins, compatibility and functionality can be inconsistent, and your favorite add-in might not even be available. The potential loss of these essential tools is a significant reason to stick with the classic version.
• Performance Considerations: On older or less powerful hardware, the classic Outlook often performs better than the web-based version. Native applications generally have lower overhead than web applications because they interact directly with the operating system. This is especially important if you are running multiple applications at once.
• Control & Customization: Some users prefer the greater level of control and customization offered by the classic Outlook. You can fine-tune settings, tweak the interface, and manage your data in a way that’s not always possible with the newer web-based version.

Microsoft’s Perspective (Why the Change)

So why is Microsoft so eager to move everyone to the new Outlook? There are several likely reasons, and understanding them helps to see the bigger picture.

• Modernization & Platform Consistency: Microsoft is striving for a consistent experience across all devices and platforms. Web-based applications allow them to deliver the same functionality and interface regardless of whether you’re using a Windows PC, a Mac, a Chromebook, or even a mobile device. This simplifies development and support and creates a more unified user experience.
• Simplified Development & Maintenance: Maintaining multiple versions of the same application is a massive undertaking. By focusing on a single web-based version, Microsoft can streamline its development process, roll out updates more quickly, and reduce the complexity of managing its software. This means faster feature additions and security patches for everyone.
• Integration with Cloud Services: The new Outlook is more tightly integrated with Microsoft 365 and other cloud services. This allows for seamless collaboration, data sharing, and access to a wide range of cloud-based features. By moving to a web-based platform, Microsoft can leverage the full power of its cloud ecosystem.
• Cutting costs: Web-based applications are cheaper to maintain.

In summary, while users may prefer the familiar and functional classic Outlook, Microsoft is pushing towards a web-based model to streamline development, improve cross-platform consistency, and deepen integration with its cloud services. Understanding both sides of this equation is key to deciding whether to stick with the classic version or embrace the new one.

1. Direct Link: The easiest way to find the classic Outlook is by using this direct link to the Microsoft Store: Microsoft Store link

This will automatically open the Microsoft Store app on your computer and take you directly to the classic Outlook listing.

4. Office Installer: After clicking “Install,” the Office installer will launch. This installer will download and install all the necessary files for the classic Outlook. The process may take some time, depending on your internet connection speed and computer performance. Let the installer finish its operation.

Blocking the New Outlook App on Windows 11

Stopping the Switch: How to Block the New Outlook App on Windows 11

Installing the classic Outlook is only half the battle. Microsoft is actively trying to move users to the new Outlook, and it may attempt to switch you over automatically, which can remove the switch within the app. To prevent this from happening, we need to modify a setting in the Windows Registry.

Important Disclaimer: Editing the Windows Registry can be risky. Incorrect changes can cause system instability. It is strongly recommended that you back up your registry or create a system restore point before proceeding. If you are not comfortable editing the registry, seek assistance from a qualified technician.

With that warning in mind, here’s how to block the new Outlook app:

1. Accessing the Registry Editor: Open the Start menu and type “registry editor.” The “Registry Editor” app should appear in the search results. Click on it to launch the program. You may be prompted to allow the app to make changes to your device.

2. Navigating to the Correct Key: In the Registry Editor window, you need to navigate to a specific location, or “key,” that contains the setting we want to change. Copy and paste the following path into the address bar at the top of the Registry Editor window and press Enter:

   Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences

   This will take you directly to the “Preferences” key for Outlook.

3. Modifying the “UseNewOutlook” Value: In the right-hand pane of the Registry Editor window, you should see a list of entries. Look for an entry named “UseNewOutlook”. If you don’t see this entry, right-click in the right-hand pane, select “New,” then select “DWORD (32-bit) Value,” and name it “UseNewOutlook”. Double-click on the “UseNewOutlook” entry to open the Edit Value window.

   In the “Value data” field, change the value to 0 (zero). Click “OK” to save the changes.

4. Restarting the PC: Close the Registry Editor and restart your computer. This is necessary for the changes to take effect.

After your computer restarts, the automatic switch to the new Outlook should be blocked. You can now use the classic Outlook without worry.

Troubleshooting and Advanced Tips (Optional)

Advanced Tips and Troubleshooting

Even with careful instructions, things don’t always go as planned. Here are a few troubleshooting tips and advanced considerations to keep in mind.

• What to Do If The Registry Change Doesn’t Work:

  • Double-Check the Registry Key Path: Make sure you entered the registry key path correctly. If you have older versions of Office installed, the number 16.0 may need to be a lower number.
  • Confirm Value: Make sure the value for UseNewOutlook is set to 0. Sometimes the value may be 1 or blank.
  • Restart Again: Make sure to restart your computer after changing the value in the registry.

• Alternative Email Clients (Brief Mention): While the classic Outlook is a popular choice, many other capable email clients are available. If you’re finding it difficult to stick with the classic Outlook or simply want to explore other options, consider alternative clients like Mozilla Thunderbird or Mailbird.

  • Mozilla Thunderbird: This is a free and open-source email client known for its flexibility, customization options, and strong privacy features.
  • Mailbird: Mailbird is a paid email client that emphasizes speed, simplicity, and integration with other productivity tools.

• Staying Updated (Carefully): Be aware that Microsoft may release future updates that attempt to re-enable the new Outlook. You may need to periodically check the registry setting to ensure that it hasn’t been changed back to the default value. Staying updated can improve computer security and is not something to avoid entirely. Just pay close attention to when the new Outlook reappears when you do your updates.
