Microsoft Teams Meeting support for 20,000 attendees

Teams will soon support up to 20,000 meeting attendees as view-only participants for tenants with the Advanced Communications add-on.

This feature will begin rolling out at the end of November 2020.

Currently, Teams meetings are limited to 300 users. If someone tries to join a meeting after it reaches capacity, they are unable to do so.

If you choose to purchase the Advanced Communications add-on, users who are assigned an Advanced Communications license will be able to host a meeting with up to 20,000 people as view-only attendees after a meeting has reached capacity.

• The inclusion of view-only attendees will not impact the normal interaction available between regular attendees who joined before the meeting reached capacity.
• Once the maximum Advanced Communications limit is reached, no additional view-only attendees will be able to join.

View-only attendees can use Teams in the browser or a Teams desktop app (Windows or Mac). Microsoft is expected to support Teams mobile apps in mid-December.

• View-only attendees do not need the Advanced Communication plan to join the meeting in a view-only capacity. However, they do need permission to bypass the Lobby based on set Lobby Policies or Options.
• View-only attendees will follow all lobby and security policy mechanisms.
• View-only attendees will do so with limited access to capabilities. For example, view-only attendees will be able to listen to all audio and view a screen or window shared during the meeting. However, they will be unable to share audio or video, and they will be unable to see chat or other applications that are shared during the meeting.

Meeting organizers will not be able to see view-only participants in attendee counts or reports; this feature does not support the e-discovery of data. Organizers cannot remove view-only attendees from a meeting.
