I'm trying to figure out why Outlook 2016 suddenly started displaying email attachments in a single vertical column under the email subject line, rather than having 4 or 5 attachments displayed in horizontal single line orientation as it has always been. I can't find any setting to change the view back to the horizontal orientation as I don't like to have to scroll down to see all the attachments. The regular view settings (compact vs single line) have no effect on the attachment view.
