Re: Is there a way to permanently uncheck the box which saves your sent private messages?
Holly, I am not an expert on such things, but I am not aware of an option such as your describe.
However, there is an easy way to delete all the messages in your Sent Folder without checking each box for each message. Just click on "Empty Folder." I have made a screen capture and put a red arrow to point where you can find those words.
