Hi scott136,
I'm sorry, but I'm not clear on what it is you wish to do. Do you have one email account that you have set up in the Live email client that you want to set up and use on your InMotion Hosting account? Or, do you have a Microsoft Live email address you are asking about? If the email address is the same, please see our tutorial on transferring Emails from your old host to InMotion Hosting. If you are asking about a Microsoft Live email address, you would need to forward those emails to your email address that you set up in your hosting account here at InMotion Hosting.
Please feel free to either update your question or add a comment below with more details. We'll be happy to assist further.
Regards,
Christi N.
