!In the latest versions of Windows 11, the Outlook New app is installed automatically.
If this does not suit you, we will tell you how to block this automatic installation.
To block Outlook New auto installation in Windows 11, just follow the next steps:
- If Outlook New is already installed, you should uninstall it first.
To do this, in Windows PowerShell running as administrator, run
Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName
or Get-AppxPackage *Microsoft.OutlookForWindows* | Remove-AppxPackage -AllUsers if the first command fails.
- Then launch the registry editor by pressing Win + R and running regedit.
- In the registry editor, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\Orchestrator\UScheduler_Oobe and delete the OutlookUpdate subkey by right-clicking on it and selecting Delete from the drop-down menu.
- Then go to HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\outlook\preferences and create a DWORD parameter NewOutlookMigrationUserSetting and set the value to 0.
This will block the transition to the new version of Outlook in Office 365.
- Then go to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General and create a DWORD parameter HideNewOutlookToggle with a value of 1.
This will remove the switch with the offer to try the new Outlook in the Outlook desktop application.
- In addition, you should stop using the classic built-in Mail application, because after launching it, the installation of Outlook New will be initiated again.
- After completing all the steps, you should restart your computer.
