Outlook express guru? lol (help!)

Ok, just started using outlook express. I have one question: How do i download read messages. What i mean is, when i start up outlook express, it shows downloads all of my unread emails, but i want to download the rest of my mail from my yahoo inbox. anyone know how to do this?

If you still don't understand...look at this illustration lol:

Import them.

Well... nevermind... there are a lot of things you can do and a lot of them are painful. The easiest thingi to do would be to just set all those emails as unread and let it download them.

Just ran Outlook (which I never use) and I found that you can just click + drag messages to another folder, or to the desktop.

Of course, this means nothing if you're getting your Yahoo email through Yahoo.com and not Outlook Express.. (Not even sure if you can do that, actually)
