When I made the switch to Vista, I setup Vista Mail as my newsreader

not going to be any more (or perhaps little) development on Vista
mail with the attention going to Windows Live Mail Desktop which begs
the question, if I were to install Live Mail and set it as my default
newsreader, will Outlook automatically open it rather than Vista Mail?

Try it and see.
