For several years I used Outlook Express on a Windows XP computer to manage my e-mail.

Some days ago I started using another computer with Windows 7 and installed Windows Live Mail, so that I could manage my e-mail on it too. But I started noticing that, while Outlook Express on the first computer received all e-mail, Windows Live Mail on the second computer did not.

I would like to fix this. Can someone help me, please?
