Outlook Express is replaced in Vista by Windows Mail. They are very similar,
but not identical. (I use Windows Mail as a Usenet Newsgroup reader, and
it's slightly inferior to Outlook Express for that, in my opinion.)
Why do you need Outlook Express? If it's just for email, I suggest using the
full version of Outlook instead. (That's if you have a version of Office
2007 that includes it. The Student/Home version of Office 2007 does not
include Outlook.) I haven't used Outlook 2007, but Outlook 2003 is a much
better email application than Outlook Express.
There may be better email applications available, but I've stuck with
Outlook, as it was used by my employer.
Hope this helps.
