They don't stay there, though. I don't know whether they don't move to the Sent box until the recipient reads them or what triggers it, but I've noticed that, too, and wondered, and when I went back the next day the message had arrived safely in the Sent box after all.
Wonder if anyone has an explanation for the way that works....
Leslie is right - they sit in the outbox until the recipient reads it. The nice thing is that you can edit it until then, so if you're say... sending a typo filled PM to Gene... you can fix it before he gets on and reads it :lol:
