Something happened the other night - what, I'm not sure - and all of a sudden I couldn't see any info in the message pane for the Inbox of one of my email accounts. All the info showed in the message pane for all the other folders in both email accounts. I've gotten most of the info back in the message pane for that inbox by selecting which columns to display. The only column I am missing is the column for the email Subject. The "Select which columns to display" list doesn't include the Subject option. How can I get the Subject column back?
