Microsoft is rolling out the new Outlook app to Windows 10 and 11 devices, starting January 30, 2025. This article provides comprehensive guidance on blocking its automatic installation, as well as uninstalling and removing it from your devices.
The new Outlook app, a web-powered version, is designed to replace the classic Outlook. However, if you prefer the classic version or wish to control the update process, this guide is for you. We'll cover methods to uninstall the new app, prevent future installations, and even block automatic migration in your Microsoft 365 account. This is critical knowledge for users who want to maintain their preferred Outlook experience and avoid unwanted changes.
Whether you're on Windows 10 or 11, we've got you covered. Let's dive into the steps you can take!
Uninstalling How to Remove the Forcefully Installed New Outlook App
If the new Outlook app has already been installed on your Windows 10 or 11 device, you can uninstall it using a straightforward PowerShell command.
Follow these steps:
1. Open PowerShell as an Administrator by right-clicking the Start button and selecting 'Terminal (Admin)' or 'PowerShell (Admin)'.
2. Run the following command:
`powershell

2. Extract the contents of the ZIP file using 7-Zip or another file archive utility.
3. Run the extracted .REG file.
4. When prompted, accept the confirmation to apply the changes.
After running the script, the new Outlook app will no longer automatically install on your Windows 10 or 11 device.
The ZIP file also includes an UNDO file to restore the automatic installation, should you change your mind.

For advanced users, here's how to apply the Registry tweaks manually. This is useful if you prefer not to use a script.
1. Open Registry Editor (regedit).
2. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
3. Create a new DWORD (32-bit) Value named 'DisableNux' and set its Value data to '1'.
1. Open Registry Editor (regedit).
2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer
3. For Windows 11, delete the 'UpgradeToNewOutlook' key if it exists.
