Maybe they should have called it 'Blackmail' not 'Hotmail'.
I've been using Hotmail since it came out virtually,I still use it,but, not so much nowadays.
How they can allow their email service to become a spam vehicle,then,'blackmail' users to get it off,or else it stays,just STINKS.
As for no going back to Hotmail from Outlook,it's that same attitude from Microsoft,that says,of W8,we are NOT going back to the Start Menu.
I don't like it,but,if they want to follow in Apple's footsteps,by making PC users install only Microsoft Store apps,then who am I to argue with them.
The result will be only to the good of Linux.
