I have twice tried to send Amy a private message to ask a question and both times the messages stay in my outbox and not in the sent box so I am guessing she has never received them.
What the heck am I doing wrong???
I’ve found that they stay in your box until the other person logs on.
I went and checked my boxes to see what the out vs. sent looks like. I sent Hildie a message the other day and it’s in my sent box, along with replies i’ve sent on other messages. And i noticed that my out box is the one that is empty. I think they must go from out to sent after a period of time, perhaps? she may have gotten them, i guess we’ll wait to find out… 
Yep, they stay in your outbox until the person opens it… then it goes to sent items folder… great way to spy
Hi Dee!
Yup, they’re right! I just now noticed your message, and am reading it. I’ll respond soon! Sorry for the wait, I’ve been neglecting my PM’s…
I noticed that too for the first time the other day. Now it all makes sense
