I recently received a mail directed to a whole bunch of people which I accidentally dropped in the outbox (I think) instead of an archive directory where I wanted to put it.
The mail disappeared and moved to my sent items, which is scary because I don't want to send it to all these people. However when I try the same thing again with another mail from a friend directed just to me... nothing happens as it stays in the outbox.
Firstly: no one reported receiving the mail twice, first the original and then from me. Secondly: this makes me wonder if I just dropped it into the Sent Items directly instead of the outbox and just feared the worst.
So basically the question: IF I drag and drop a mail from the inbox to the outbox, what should happen?
Nothing will happen - Outbox is just an eye candy. A message can be submitted from any folder; Outlook moves messages to the Outbox just to avoid confusing the users.
