Someone sends you mail, you don't own the reply, but you know who does. Today you reply and include the actual owner... then your inbox is flooded with the back and forth from the connection you just forged with a discussion that doesn't apply to you. Couldn't I just BCC myself in the origional reply?
Maybe I'm missing something in outlook, but I'd love a reply button that effectivly removes me from the thread such that the new participants would actually have to manually add me back.
It just strikes me that there's a lot of effort going into products and features that help organize e-mail clutter, but not so much thought going into improving e-mail work-flow such that it becomes less of a problem.
