I need help please to stop the new outlook from automatically installing and replacing my windows and calendar app. I have uninstalled the new Outlook 4 times today. Every time I launch the old mail and Calendar app the new outlook automatically installs without my permission. It stops me from using the old app. This is very annoying. I don't want the new app. Is there any way to stop this from happening? Your advice would be appreciated.

Kind regards

Chris

What worked for me was deleting the new Outlook's executable ("olk.exe") from "C:\Program Files\WindowsApps\Microsoft.OutlookForWindows".

Once it's gone, it can't forcibly launch anymore when you open Windows Mail.

You first need to take ownership of the "WindowsApps" folder, then after deleting/renaming the .exe, restore the ownership back to "TrustedInstaller" (to prevent any potential issue down the line).

    Thank you very much Nick for this suggestion. I tried it, but sadly, the new outlook always launches instead of the old mail app and takes over. I am not sure if using an administrator account makes any difference.

    Once I uninstall Outlook and launch Mail then it will work as long as its not closed. As soon as its closed, then the second time its launched, new Outlook will take over.

    Kind regards

    Chris

    Open the new Outlook, then navigate to the Installation Path unsing the Task Manager (Expand new outlook process and right click on the main prcess -> open file path) and delete everything.

    The enemy is listening!

    Sure enough. Woke my PC this morning and the Mail app was gone from my task bar and New Outlook was not in the list of removable programs. Started Mail from the Start Menu. Very slow to start but then started up after which New Outlook showed up in the removable programs list.

    They are funking with us!!!

    Hello everyone,

    I was facing the same issue with the New Outlook being forced upon me, and I found nothing seemed to work long-term. I also prefer the old Mail app for its 'Focused' and 'Other' sorting features.

    To tackle this, I wrote a Python script that automatically uninstalls New Outlook anytime the Mail app is launched or closed, and it even sends uninstall requests at adjustable intervals while the Mail app is open.

    It's not the most elegant solution, but it works reliably. If you're in the same boat, feel free to try it out. I've shared the code on GitHub: New Outlook Killer

    I hope this helps anyone who's been struggling with this issue!

    Best regards,
    Thepastafarian
