Assessment Reasoning
The rollout is in progress and timeline was extended from mid-September to end of October, reducing urgency. No admin configuration is required, but awareness and optional communication to event producers is advised. End users are unaffected; only producers hosting town halls might use the new backup stream option. Effort is low as the feature is on by default.

📢 Official Microsoft Message Center Announcement

(Updated) Microsoft Teams town halls now support backup Real-Time Messaging Protocol (RTMP) streams
Message ID: MC1261595 (Updated)

Updated September 22, 2026: We have updated the timeline. Thank you for your patience. 

[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:]

General Availability (Worldwide, GCC): Rollout begins late April 2026 and completes by end of October 2026 (previously mid-September)

[How this affects your organization:]

Who is affected:

  • Organizers and producers hosting Microsoft Teams town halls using RTMP-based production workflows

What will happen:

  • Organizers can configure a backup RTMP stream during event setup using Teams Meeting options in Production tools.
  • If the primary RTMP stream fails, Teams will automatically fail over to the backup stream with no manual intervention.
  • There’s no change to the attendee experience.
  • The feature is available by default; no admin configuration is required.

[What you can do to prepare:]

  • No action is required.
  • Optionally, update internal event-production documentation and notify event producers of this new resiliency option.
