By default, the items that you add to the lists and libraries are displayed only when you are viewing the meeting where the items were added.

To have several meetings to target the same objectives, we can convert the objectives to series items.

Procedure:

Click 'Objective'--on the ribbon, click 'List'--Click 'List Settings'

I can convert the Agenda and the Document Library to Series Items, but not Attendee. Why?
