I've seen similar behavior when the system isn't shut down cleanly after setting something up, or the system just "thinks" it didn't shut down cleanly. Try this. Open it up and let it go through it's config. Then close Live mail through the menu, not the "x". Then logout of the system. Then shut it down. When you are logged out you may need to select "switch user" to see the shutdown button. Power the machine back on and see if it still does that.
