I believe that's the way it works ... that's what happens for me ... I can tell if someone has "picked up" the PM that way.
Yeah, I find that useful as I can tell if someone is ignoring me or not :roll:
But, perhaps a better idea would to have an Inbox and Send Item folder and to substitute the outbox for an icon of somekind to indicate it has yet to be read?
Good idea too ... I don't see it as a big issue either way ... but just because I'm cool with it now, doesn't mean others don't have valid objections.
