Teams meetings to support view-only attendees
Microsoft Teams will soon support up to 20,000 meeting attendees as view-only participants when the attendee is accessing a meeting via a Teams desktop application (Windows or Mac), Teams on the web, or Teams mobile (Android and iOS). This feature applies to those with E5, E3, A5, or A3 licenses.
This feature is associated with Microsoft 365 Roadmap ID 65952.
When this will happen
- Phase 1, a temporary increase to 20,000 view-only participants runs from late February through the end of June
- Phase 2, view-only participant capacity will revert to 10,000 view-only participants the first of July
How this will affect your organization
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. With this update, meeting organizers who are assigned an appropriate license will be able to host a Teams meeting that has overflow capacity.
- Up to 20,000 view-only attendees may join a meeting from late February through the end of June
- Up to 10,000 view-only attendees may join a meeting after July 1, 2021
Similar to Teams Live Events limit increases, during this peak remote work time, we have temporarily increased attendee limits.
Meeting organizers will not 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.
When a meeting organizer enables this overflow feature:
- After a meeting reaches capacity (300 users), people will be able to join as view-only attendees, with the maximum number limited by the phase
- View-only attendees will not impact the normal interaction available for regular attendees (those who joined before the meeting reached capacity).
- Once the view-only attendee limit is reached, no additional view-only attendees will be able to join.
View-only attendees do not need a special SKU 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 have limited access to meeting features. 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.
What you need to do to prepare
This feature is OFF by default for your users.
You may use PowerShell to enable this feature for your entire tenant while you prepare to assign the licenses.
