Is There Any Way To "unsave" A Email That Has Been Saved, To Bring It Back To The Regular Email Folder
So It Is Not Possible If I Want To Change It From A Saved Draft To An Unsaved Draft Without Sending It As A Message?
well if you want to unsave then wouldnt it be the same theory as you not needing the files anymore? so why not just delete it
