Stop automatically installing the new Outlook

Hahaaa!

Thanks to Lakshmi Nomis hint, here's solution that works for me (Windows 10):

1. Right click on Start Menu and choose Apps and Features
2. Uninstall Outlook (new)
3. Open File Explorer and navigate to C:\Program Files\WindowsApps
4. Create new folder named Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe
5. Right click on newly created folder and choose Properties
6. Select Security tab, then Advanced
7. Click on Disable inheritance and choose Remove all inherited permissions from this object
8. Click Apply and Yes

And that should be it... no more Outlook (new) on your PC!

What's even worse is I have auto app updates feature turned off, but it installs the new app anyways even though it's not supposed to update any apps.

Hello Windmill Photos,

Good day! Thank you for posting to Microsoft Community. We are happy to help you.

After Microsoft's update, since New Outlook is a Windows component, even if you uninstall it, New Outlook will still download back as soon as you update your Windows system next time. But Outlook and New Outlook can already be used in parallel in your system, so this will not affect your use of Outlook.

We hope you find the above steps helpful, if you have any questions or concerns, please feel free to contact us!

i do not want new outlook on my pc can you please help me just use the normal mail app and not new outlook?

hi corey,

I deleted these files however after 10 seconds of using the old windows mail, outlook(new) had reinstalled itself again. What am I doing wrong? it was definitely the correct files as you stated above.

You can create a batch file that uses a wildcard for the username to delete files in a specific folder across all users. Here's an example of how you can do it:

batch
@echo off
set folderPath=C:\Users%username%\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration\*
del /Q "%folderPath%"
echo Files in %folderPath% have been deleted.
pause-------------------------------------------------------------- This script does the following:

1. @echo off prevents commands from being displayed in the command prompt.
2. set folderPath=C:\Users\%username%\specific_folder\* sets the folder path, where %username% is a wildcard that automatically gets replaced with the currently logged-in user's username.
3. del /Q "%folderPath%" deletes all files in the specified folder quietly (/Q).
4. echo Files in %folderPath% have been deleted. prints a message indicating that the files have been deleted.
5. pause keeps the command prompt window open so you can see the message.

You could then save this file in the startup shell, just press the Windows key + R then type Shell:startup then OK

This should take you to the folder where you could save the batch file which will run each time a user logs on.

Hope this helps :)
