separating windows live mail accounts

[#1]

Hi
I have just set up windows live mail for mine, my husbands and sons email accounts. I did this by adding another email account where prompted during the set up but now when I open up windows live mail all three email accounts are shown and so we can all read each others emails. Not always a good idea!
Can anyone advise on how I can separate these so that we each have to login to our own email accounts?
Thanks.

I suspect you would need to have separate windows logins

If you start windows live at www.live.com you will get to the attached page.
You can then log in to your account but do not tick the "Keep me signed in" box. After you logoff Windows Live other users can use the same method to access their unique account.
