Hello!

Could you please help me with uninstalling the new Outlook from my computer (Windows 11) as I would still like to use the outdated Windows Mail app?

What I tried:

  1. Uninstalled the new Outlook from settings (Windows Settings > Apps > Installed apps)
  2. Blocked new Outlook preinstallation via:
  • Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName
  • Remove-AppxPackage -AllUsers -Package (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName
  1. Blocked new Outlook installation as part of Mail and Calendar deprecation via:
  • Get-AppxProvisionedPackage -Online | Where {$_.DisplayName -match "microsoft.windowscommunicationsapps"} | Remove-AppxProvisionedPackage -Online -PackageName {$_.PackageName}
  • Remove-AppxPackage -AllUsers -Package (Get-AppxPackage microsoft.windowscommunicationsapps).PackageFullName

All shell commands were run as Administrator and I also deleted OutlookUpdate folder in Registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\Orchestrator\UScheduler_Oobe\OutlookUpdate

I would appreciate any advice regarding my question :)

    with so many complaints about outlook (new) I think Microsoft should provide a quick fox for people to get rid of it. I never asked for it. When I look at the list of installed apps, outlook new is not there. however, when I initiate an email for a website, outlook new opens. ****?

    Microsoft should stop doing this to its users, rather than forcing every end user to learn these complex operations. This is ridiculous. It's the vendor that's responsible, not the users.

    This the most ridiculous, convoluted, too many steps answer that could be given. Plus, the answer states, that the codes may not work properly and you have to enter them manually - what a stupid answer!!! Just tell us how to get rid of f___ing Outlook permanently and Microsoft should not be allowed to let it automatically take over your device - let's get some PRIVACY regulations petitions started Microsoft customers.

    THERE IS NO REASON THAT WE SHOULD NOT BE ABLE TO CHOOSE TO ELIMINATE OUTLOOK, EXCEPT FOR THE FACT THAT MICROSOFT WANTS COMPLETE CONTROL OVER OUR EVERY MOVE!!!

    Dear Aetherum,

    Thank you for your patience and cooperation.

    First of all, please understand that starting from 2024, new Windows 11 devices will come pre installed with new Outlook as the default email application. Reference: Outlook for Windows: The Future of Mail, Calendar, and People on Windows 11 - Microsoft Support

     

    Currently, if you wish to continue using Mail and Calendar without automatically redirecting to New Outlook, additional settings are required. Please refer to the following steps:

    Note: The highlighted area is the current user name (# comment bar can be deleted)

    1.Replace the YOURUSERNAME with actual username of your PC.

    2.Select all the codes below and copy them.

    3.Open PowerShell with administrator privilege, you can search PowerShell in search bar, right-click it and choose to run with administrator.

    4.Once PowerShell is opened, paste the codes into it, and press enter.

     

    Define the folder path to operate on

    $folderPath = "C:\Users\YOURUSERNAME\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration"

    Define the path of the file to delete

    $fileToDelete = "$folderPath\settings.json"

    1. Delete the specified file (if it exists)

    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."

    }

    Get the username of the current logged-in user

    $currentUser = [System.Security.Principal.WindowsIdentity]::GetCurrent().Name

    2. Get the Access Control List (ACL) of the folder

    $acl = Get-Acl -Path $folderPath

    Define a new access rule to deny write access for the current user

    $denyWriteRule = New-Object System.Security.AccessControl.FileSystemAccessRule($currentUser, "Write", "Deny")

    Add the deny write access rule to the folder's ACL

    $acl.AddAccessRule($denyWriteRule)

    Apply the modified ACL to the folder

    Set-Acl -Path $folderPath -AclObject $acl

    Output the result of the operation

    Write-Host "Write access denied for $currentUser on $folderPath"


    The code performs two actions. You can also perform these actions manually if your code does not perform them correctly.

    1. deletes the settings.json file inside C:\Users\YOURUSERNAME\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Migration

    2. Add a deny write rule to the Migration folder security permissions.

     

    Hope this help you, please feel free to let me know how it goes. 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.

    Hello.

    First timer here!

    I suddenly had problems with Outlook a few days ago in that cant send mail but can recieve it. One of the many things I tried was to toggle on to new Outlook. Hate it! But... I could send emails again. That lead me to think, ah conflict beween new and old.

    So uninstalled new. Sadly still cant send emails out and that irritating toggle button is till there. Needless to say, if I toggle on new gets downloadd again.

    Can Addie.C suggest how I can ger rid of that toggle button and any other trace of new Outlook gets removed from my laptop.

    In desperation,

    Anne
