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).

    does not work because after office updates come through you’ll be right back where you were there will be the Olk.EXE right back where it used to be

    It's good that you have deleted "olk.exe" As an extra step, you can log in as administrator and make a new empty text document on your desktop. Rename it to olk.exe and copy it back to the same folder.

    When the pop up below appears with the ultimatum, click on "open Outlook"., hopefully, the new Outlook won't be able to launch and you should be able to continue to use the old Mail app (at least until the next windows update). This is what I have been doing.

    Kind regards
