Linking Live Mail Between Several Platforms

Hi all. Any help gratefully received. I have a Live Mail address that I access from my laptop, my Surface 2 and my iphone 5. My problem is at the moment I have to monitor the same account separately across each platform. i.e. if I delete a mail from the account using my Surface 2, it still remains on my laptop and on my phone. Are there settings I'm missing that will allow me to link the account properly across all platforms so that if I make adjustments to one account it displays on all? Thanks for all help.
