ok so maybe i am missing somthing really obvious, but how do i delete sent messages from my message folder. i tried to put them in my save folder and delete them that way but it is not working. thanks in advance.
PMs are saved centrally for both sides. They don't actually allow you to delete a sent PM because it would then delete the PM on the recipients side as well. So, short answer: no, you can't delete sent PMs.
