Update....................
I have located a way to actually uninstall Mail and Calendar.
It came from howtogeek article.
It involves Powershell run as admin and using the Get-AppxPackage command line.
Result : Mail and Calendar apps are uninstalled.
Yes, Calendar has become the victim of collateral damage. I don't use it, so that's ok for me.
The tutorial also provides method to restore the apps.
I am not sure if I am allowed to post the whole article.
So, I'll stop at this point.
If the mods say it's ok to post it, then I'll be delighted to comply.
Meanwhile, those who are interested will have to google for it yourself.
