Outlook 2016 -I need to display a list of required attendees

In Outlook 2016 I  want to display the list of all required attendees. I can do that in the calendar view, but the list is too long and does not display fully. 

So either  I need to increase the space  there or use the Meeting view, but there is not tracking under 'Show', just Appointment and Scheduling Assistant. Sure, I can  use the Scheduling assistant to display the little pic to the left of  each attendee to illustrate if required or not, but I'd like it to appear on the Appointment tab as Required: A, B,C,D,,....

How do I achieve either of the two?
