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).

    I installed the old Windows Mail and calendar app on my new Windows 11 PC. It only took 5 minutes. This time, I uninstalled the new Outlook, ran the ourlook remover tool bat file, and installed the old Mail app from an archive.

    The old Windows Mail synced properly with my Microsoft Exchange Active sync account. Unfortunately it doesn't sync with my normal Hotmail IMAP account. (It did sync with my old Win 10 PC). It looks like Microsoft have pulled the plug for Hotmail accounts running on the old Mail app. I didn't test it with Gmail.

    I will probably keep the old Mail app runing as long as it lasts. Then I will probably switch to another e mail client (Thunderbird, Wino Mail, eM Client or Blue Mail and Calenda, etc.r). I tested Blue Mail today and was impressed that it can sync with Microsoft exchange active sync.
