By default, Teams events supports up to 3,000 interactive attendees or up to 10,000 attendees in a view‑only experience for each event. Interactive events allow features like chat, reactions, Q&A, and polling, while view‑only events are designed for large audiences primarily watching the broadcast.
For larger, streaming, non-interactive events, capacity can be increased up to 100,000 attendees by assigning additional capacity licensing to the event organizer.
