Outlook *Express*?
Outlook *Express*!!!
Lets be fair here... this abortion of a virus propagator and occasional e-mail client has no right to still exist, let alone to be used for anything even remotely, feasibly, possibly important. Even MS have tried to disown it as much as possibly and, very sensibly, re-wrote something pretty much from scratch for Vista (incidently they also fixed the insanely stupid "everything all in one file" storage system in the Vista mail client as well).
Anybody that still uses it really gets what they deserve.
