I'm not exactly sure that Outlook can burn in hell, for various reasons:
1) It is a soulless, life-sucking force that never really dies. Therefore it's final destination is the bowels of your Hard drive.
2) It is clearly one of the strongest organisms around right now: Witness that it is one of the biggest spreaders of Viruses known to the 'net, but doesn't seem to suffer from these viruses itself: it therefore must be a carrier. And forgive me for saying so, but anything that can spread that can be a carrier for that much virulent mayhem has to be damn near impossible to kill. Even after running over the CPU with a truck, it will still sit and stew in silent, vengeful patience, for its reincarnation. If it can't die, it can't go to hell.
3) Re-incarnation: IE, every time you use the OEM re-building/re-boot software that is supposed to be used after the hard drive takes a big stinky one, Outlook is there, and gets re-born anew. Perhaps re-incarnation isn't the proper word to use in talking about something that cannot die, but Cloning doesn't really cover it either, since it comes back fully matured and developed.
4) If it doesn't have a soul, cannot be killed, and is the carrier that spreads mayhem, disorder, and enough general badness that it can be essentially considered the harbinger of Cybernetic death and eternal chaos, I can think of only one thing this can mean: Outlook express is the digital Anti-christ. It therefore cannot burn in hell, since hell is essentially its rightful domain, and it's trying to win over as many machines as it can while they are still here.
