My daughter is trying to login to her account but is getting " That Microsoft account doesn't exist. Enter a different email address or get a new account " We have tried to recreate but dont have the option to create a hotmail.co.uk account which it was. We would like to keep her hotmail.co.uk account as all the family have the same....thanks in advance.
