Stop automatically installing the new Outlook

Found this on the Manage background activity for apps in Windows

(Maybe it will work, have to test it for a longer period.

This info is chrystal clear written in WIN 11 Pro by developers of MS).

Applies To

Some apps let you manage background activity, which controls what they can do when they're in the background and not actively in use.

Apps that can run in the background can send and receive notifications, sync and update information

stay up to date. If you notice that an app is using a lot of battery when running in the background, you can change the setting for apps that allow it.

Select the Home button, then select Settings > System > Power & battery > Battery usage.

For an app that allows you to manage background activity,

select More options > Manage background activity.

On the settings page for that app, change the Allow this app to run in the background setting.

Here's an overview of each option:

Always: The app is always allowed to run in the background, receive information, send notifications and stay up to date,

even if you are not actively using it. However, it may use more energy as a result.

Optimized for energy consumption (recommended): Windows determines what is best to save the most energy, while still allowing the app to receive notifications and update periodically.

This option can limit an app that uses more power.

Never: When you're not actively using the app, it won't run in the background.

You won't receive notifications or updates for the app, but this will save you the most energy.

It seems that the New Outlook is being shoved down the throat of every user at all costs.

As a user, you apparently no longer even have control over your own computer, because MS determines what is good for you.

This is once again clearly proven by the possibility in the Reg-

editor to block Outlook updates suddenly been disabled by MS crew, changing the Reg-editor, specific this part.

I hereby warn MS that, if necessary, I will make it my life's work to have this sick compulsion eliminated by more powerful authorities than the folks of MS.

I think Brussels is already rubbing his hands warm with the idea of another demolitionhammer mega-process to fill the EU treasury with even more money taken out of the pockets of arrogant administrators and shareholders of MS.

Another recordfine for a arrogant tech-giant?

MS DOES NOT DICTATE THIS WORLD AND CERTAINLY NOT WHAT WILL or SHALL NOT BE INSTALLED ON MY PC.

PEOPLE ALL OVER THE WORLD.... LOOKOUT FOR OUTLOOK!

MS: DON'T YOU DARE TO CONTINUE THIS WAY

1. Right click on WindowsApps folder and choose Properties
2. Select Security tab, then Advanced

3. In header section underOwner click on Change

4. Enter your user name and click Check Names (it will find users object name)

5. Click OK then Apply

this way kind of works...but sometimes it seems they install outlook again:

1. uninstall outlook (I mad a powersell script. I also made a shortcut on the desktop to run it):

#requires -runasadministrator

Get-AppxPackage -AllUsers | Where-Object {$_.Name -Like '*OutlookForWindows*'} | Remove-AppxPackage

Write-Host "Press any key to continue..." -NoNewLine

$null = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

2. create the outlook directory (in special apps folder) and remove all permissions to it. This involved:

• taking ownership of the parent directory (in the dir's Properties->Security->Advanced tab)
• (see below for location)
• create the new "outlook" directory
• remove inheritance (in the file's Properties->Security->Advanced tab) from the new directory
• remove all "permission entries" (in the file's Properties->Security->Advanced tab) from the new directory

the location of the outlook dir for me is:

C:\Program Files\WindowsApps\Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe

so first took ownership of : C:\Program Files\WindowsApps

3. another solution I found involves installing another "fake" app with the same app id of outlook. Its on github.

I have the same problem. I have tried numerous ways to avoid it. Microsoft says you can use both the old and new one, but they make an allegory. I want to use Windows Mail app instead of outlook (new) but Microsoft installs new one as you double click on mail icon. They changed the way of mail app works to install new one. the outlook (new) sucks because there are too many bugs.

They are forcing new one nearly a year and they cant solve the bugs yet.

new one cannot search all the inbox items. I have more than 20000 mails and it searches only latest 100 mails,

new one cannot show images unless it is in inbox

some folders and mails are lost

it's an edge tab instead of a mail app.

Why is Microsoft forcing us to use Microsoft edge instead of a useful mail app.

I can't work offline with new edge looking outlook (new) app.

I think it's time to bury outlook in depth of internet history.

I will be changing my mail app soon out of MS.

I just do not like Outlook, I was and still am perfectly happy with the old Mail Calendar app, and now I see MS are forcing "new" Outlook on us by the end of 2024, I must have uninstalled Outlook a hundred times, but it just keeps re-installing itself without asking and I'm getting really annoyed by that, Microsoft just don't listen to their users.
