How to uninstall Outlook (new) on Windows 11 and prevent it from redownloading when opening the Windows Mail?

Hello,

I wrote on 19 octobre:

I found out the new Outlook version is in the following folder:

C:\Program Files\WindowsApps\Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe.I prevented the installation of the new Outlook bij renaming of the folder Microsoft.OutlookForWindows_1.2024.925.0_x64__8wekyb3d8bbwe.To do this I had to become owner of the ( Hidden) folder C:\Program Files\WindowsApps.How to change owner is written here:https://www.guidingtech.com/how-to-access-windowsapps-folder-on-windows/

The slider remains.

Thats still valid, only the folder of new outlook has another name after the latest update.

I renamed both files:

Microsoft.OutlookForWindows_1.2024.1023.300_x64__8wekyb3d8bbwe

and Microsoft.OutlookForWindows_2.2024.925.0_x64__8wekyb3d8bbwe

Sadly, it is a one time solution. You can open mail once. After closing it icon pinned to task bar changed to outlook new. If I try to open mail app it redirects with an error, saying it needs to repair outlook settings.

My Windows was upgraded from 7 to 10 to 11. I do not have migrations. This solution is the only one I got working. Just onece though.

Any other suggestions?

Dear BW._1,

If you want to go back to Windows Mail, you can try the following methods:

1. Select all the codes below and copy them.
2. Open PowerShell with admin privileges, you can search for PowerShell in the search bar, right-click on it, and select run with admin.
3. Once PowerShell is open, paste the codes into it and press Enter. $username = $env:USERNAME   $folderPath = "C:\Users$username\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration"   $fileToDelete = "$folderPath\settings.json"   if (Test-Path -Path $fileToDelete) {     Remove-Item -Path $fileToDelete -Force     Write-Host "File $fileToDelete has been deleted." } else {     Write-Host "File $fileToDelete does not exist." }   $currentUser = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name   $acl = Get-Acl -Path $folderPath   $denyWriteRule = New-Object System.Security.AccessControl.FileSystemAccessRule($currentUser, "Write", "Deny")   $acl.AddAccessRule($denyWriteRule)   Set-Acl -Path $folderPath -AclObject $acl   Write-Host "Write access denied for $currentUser on $folderPath"

Hope this helps you, please feel free to let me know how things are going. If there is any deviation in my understanding, please forgive me and provide me with more details. I am more than happy to continue to help you.

All the best

Dear Addie.C,

I did exactly what you indicated to do - opened Powershell, ran it as an Administrator, pasted all of the code you provided and hit enter, then restarted my computer to make sure the changes took place, then reopened Windows Mail and, lo and behold, New Outlook reinstalled itself again. Any other suggestions??

Thanks for trying. If you do have any other suggestions I hope to hear from you soon.

Thanks again.

In a CMD with admin, type: sc.exe config appidsvc start=auto

Select Outlook For Windows as Deny. If it ask to create other rules to allow installing and running other apps, click yes.

Reboot and now you can uninstall Outlook (new)
