I might be the last person on earth who doesn't know how to do this. How do I use Outlook as my email program? I know how to use Outlook--I used it for years at my last job and I love it. My problem is (showing my ignorance here) I have email through at&t and I don't know how to connect the two, for lack of a better technical term.

I don't consider myself a stupid person, but I really haven't been able to figure this out. I tried a few years ago and gave up, and now I want to try again.
