How to Block and Remove New Outlook App on Windows 10 and 11

If you’ve installed the new Outlook app on Windows 10 or 11 but prefer to disable or remove it, this guide provides clear, step-by-step instructions to help you achieve that. Whether you want to prevent accidental launches, free up system resources, or simply avoid the app altogether, these methods will help you effectively block or uninstall the Outlook app. Before starting, ensure you have administrative rights on your Windows computer, as some steps require elevated permissions. Additionally, backing up important data or settings is recommended if you plan to reinstall or re-enable the app later.

What You’ll Need

• Administrative access to your Windows 10 or 11 device
• Internet connection (for certain steps involving PowerShell or Group Policy)
• Basic familiarity with Windows Settings and PowerShell commands (optional but helpful)

Step-by-Step

1. Identify the Outlook App Version: Determine whether you are dealing with the Microsoft Store version or a pre-installed Windows app. For the Store version, you’ll need to manage it through Settings or PowerShell; for built-in apps, different approaches apply.
2. Uninstall via Settings (for Store App):
   • Open the Windows Settings by pressing Windows + I.
   • Navigate to Apps & Features.
   • Scroll through the list to find Microsoft Outlook.
   • Click on it, then select Uninstall.
   • Confirm the uninstallation if prompted.
3. Block Further Access to the Outlook App: If you can’t uninstall or prefer to disable it, you can block access via Group Policy or Registry Editor.
4. Using Group Policy Editor (Windows 10/11 Pro or Enterprise):
   • Press Windows + R, type gpedit.msc, and press Enter.
   • Navigate to Computer Configuration > Administrative Templates > Windows Components > Store > Apps.
   • Double-click on Don’t allow apps from Microsoft Store.
   • Set it to Enabled and click Apply & OK.
   • Alternatively, to block only Outlook, you can add a specific AppLocker rule or use Windows Defender Application Control.
5. Using PowerShell to Remove or Disable Outlook:
   • Open PowerShell as Administrator: right-click the Start button, select Windows PowerShell (Admin).
   • To remove the Store app:

     Get-AppxPackage *Microsoft.Office.Outlook* | Remove-AppxPackage

   • This command uninstalls Outlook for the current user. Repeat for other user accounts if necessary.
6. Disable Outlook via Registry (Advanced):
   • Press Windows + R, type regedit, and press Enter.
   • Navigate to HKEY_LOCAL_MACHINE\\Software\Microsoft\Office or HKEY_CURRENT_USER\Software\Microsoft\Office.
   • Modify or create DWORD values to disable Outlook startup or access, such as setting DisableOutlook to 1.
   • Be cautious: editing the registry can cause system issues if done incorrectly.
7. Restart Your Computer: After uninstalling or blocking the app, restart your device to ensure changes take effect.
8. Verify the Changes: Confirm that Outlook no longer appears in your Start menu, taskbar, or system tray, and that it cannot be launched.

Common Mistakes

• Attempting to uninstall the app without administrative rights, which can prevent successful removal.
• Using incorrect commands in PowerShell, leading to incomplete uninstallation or errors.
• Misconfiguring Group Policy or Registry settings, which may impact other Office applications or system stability.
• Forgetting to restart after making changes, resulting in the app still appearing or functioning.
• Confusing the new Outlook app with the legacy desktop Outlook application, which may require different removal steps.

Tips

• Always back up your registry before making changes to avoid system issues.
• Use PowerShell scripts to automate removal if managing multiple devices or user accounts.
• Consider creating a system restore point before making significant changes, especially with registry edits.
• If you plan to reinstall Outlook later, keep track of the version and license details.
• For enterprise environments, use Group Policy centrally to manage app access across multiple devices.

Troubleshooting

If the Outlook app persists after following the steps above, consider these solutions:

• Reboot your system: Sometimes, changes only take effect after a restart.
• Check for updates: Ensure your Windows OS and Office apps are up to date, as updates can re-enable or reconfigure apps.
• Use the Microsoft Troubleshooter: Microsoft provides tools to fix app installation or uninstallation issues.
• Reinstall and then remove again: Sometimes, reinstalling the app and then removing it can resolve uninstallation issues.
• Verify permissions: Ensure you have administrator rights to make changes.
• Consult event logs: Use Event Viewer to identify errors related to app removal or access issues.
