I have a new iMac and I am stumped by email of all things. I have a preview box that shows up either on the right or at the bottom of the viewer. I want to delete it and I can't find a setting or a title for that column. I've lost my date column and I've checked date in dropdown after clicking the drop down list, it's not here. Preview is here. What can I do?
