I'm not using "the new Outlook", I'm staying with the "classic Outlook". Since I don't use it, I have to delete the app. To my surprise, it re-installs itself after a period of time. It's super annoying since I have to keep deleting it How do I stop this from happening?

    with my hack, I occasionally had windows update re-install outlook...but I think I got it working.

    In my original post I removed all permissions of the "fake" outlook dir. But instead of that try changing all permissions from an "allow" entry to a "deny" entry. So...Keep all permission entries just change the type. This involves:

    1. Uninstall Outlook
    2. in security properties advanced tab of C:\Program Files\WindowsApps , take ownership
    3. in the WindowsApp dir, create dir Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe
    4. in security properties advanced tab of the fake outlook dir, remove inheritance
    5. in security properties advanced tab of the fake outlook dir, edit each permission entry. change "type" from allow to deny

    Some time after that change, I noticed windows update downloaded outlook, but didn't/couldn't install it.

    AppData file is usually a hidden file. Must change the attribute but this worked for me. Thanks!

    To change attribute, at top of open folder click on three dots, then options, view tab, click dot to show hidden files.

    You can probably kill installation in Task Manager (Ctrl+Shift+Esc) or just uninstall it...

    Thank you for an easy and simple solution.

    Although it seems new outlook is trying to install and has hung with a full progress bar any way to stop that?
