As you say, for Agenda to see those events, they also need to be in the system calendar app. What you are asking for is for Agenda to talk directly to exchange, which technically is doable and is what Fantastical does, but requires a non-trivial amount of development work (times doing it for Google, iCloud etc as well). I’m afraid that doesn’t make it a priority at the moment, perhaps you can dig further into why the calendars show in the system calendar app but not the events. That sounds weird.
