FIX: Outlook Columns Bar (Header Bar) Disappear in Outlook 2016/2019. (Solved)
A few days ago, one of my clients contacted me to report that the bar with the column(s) titles (Send, From, Subject, Received, Size, etc.) is missing in Outlook 2019. More specifically, the row with the columns headers has disappeared after the user customized the 'View settings' and increased the ROW font size.
