Disable mail App in Windows for domain users

Hello everyone,

As we are aware Windows 10 offers mail Apps which our users use to sign in the mail providers which is against our company policy. Now I have been tasked to look for a way to keep our users from using the mail client and use outlook.

Apparently there’s a GPO setting that only applies to Vista, I’ve tried this GPO and does not work.

Then there’s a PowerShell command that will uninstall it but at the next reboot, I guess windows automatically installs Mail again.

Get-AppxPackage Microsoft.windowscommunicationsapps | Remove-AppxPackage

Has anyone tried to get rid of Mail on their corporate win10 machines?
