I have has a windows live ID for ages which is my email address
When I started Office 365 with the .onmicrosoft.com extension then changed it to my own email address it worked fine.
My machine has now packed in and when I try to log in the email address doesn't recognize the password I used when creating the Office 365 account. It does accept the old Windows live ID account but says that is is not associated with office!
I am stumped
