Microsoft accounts

Hi all.

I have a problem with my daughters Microsoft accounts which I'm hoping you can help with.

She set up an account for her X Box on my email address (without asking me first) which is preventing me from setting up my own account for Windows.

Since then she has also set up a Hotmail account with her own email address. I understand we can set up an alias on the X Box account using her email but will this conflict with the Hotmail account. The problem is she doesn't want to change her gamer tag which was set up on my email address.

Any help / advice will be gratefully received.

Many thanks in advance
