Not sure if this is the right thread but...
if they are in the outbox it means it was sent but the person hasnt read it yet and when they read it it goes to your sent box..im pretty sure thats how it works
If you're correct, thanks a lot. I had a feeling that was the case, but I wanted to make sure, so that I wasn't just stacking up a bunch of unsent PM's.
im 99.9% sure thats what it is
no worries took me awhile to figure that out too
