Mi Kids (Outlook.com) E-mail shows a message ” account is not ready”

I've been going in circles and I do not seem to get the solution to my problem. I opened a kid e-mail account for my kids but I can't get them ready. It seems that Im forced to instal a feature on windows 8 to be able to get the accounts ready but none of our computers have it. I just want them to have an e-mail account they can use via the web that is linked to mine. That's it...
