Organizers can configure this in Production tools; the feature requires no admin setup and does not affect attendees.

[Introduction]
To improve reliability for large-scale live events, Microsoft Teams town halls will soon support a backup Real-Time Messaging Protocol (RTMP) stream. RTMP is a standard live‑streaming protocol used by event organizers to send live video and audio to a streaming service, such as Microsoft Teams. This enhancement helps ensure uninterrupted broadcasts by automatically failing over to a secondary RTMP stream if the primary stream experiences an interruption. This change increases resiliency for high-visibility events without adding complexity for organizers.
This message applies to Teams for Windows desktop, Teams for Mac desktop, and Teams for the web. It is associated with Roadmap ID 554932.
[When this will happen:]

Backup RTMP Stream Implementation
If the backup RTMP stream feature is implemented without proper preparation, event organizers may face confusion during live events, leading to potential mismanagement of the streaming process. This could result in delays or interruptions in the event broadcast, affecting the overall user experience.
