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).

    The new Outlook may have been installed as part of a Windows update. If Thunderbird still works fine you can just ignore it. Or you can right click the outlook icon and select to remove from the taskbar. You can also go to settings, apps and uninstall the new outlook.

    I never knew I even had an old Outlook. I thought it was part of MS Office which I don't have. And I don't use MS Mail.

    I use Windows 10 and Thunderbird.

    A day or two ago I received a Windows notification that Thunderbird needed an update, or similar words. I dismissed the notification because Thunderbird works just fine.

    Today I noticed the "New Outlook" icon in the lower task bar. What the heck is going on?

    Why did it get installed?

    Did I have an old Outlook?

    If I roll back to a previous restore point is there some setting that will prevent New Outlook from getting installed in the first place & keep it from getting installed?

    Many thanks Dominick. Your script almost works perfectly for me:

    1. When Mail is open, I get the 'try the new MS Outlook' message, then click dismiss.
    2. The new Outlook appears on the Taskbar, but your script kills it. (Hurrah!)
    3. I close Mail, and its icon is deleted from the Taskbar.
    4. I manually re-pin Mail to the Taskbar.

    Is it possible, with your script, to stop Mail from being deleted from the Taskbar please?

    Kind regards,

    Jason
