Microsoft Teams: Secure Reliable Transport (SRT) support for Teams meetings and events

Microsoft Teams will support Secure Reliable Transport (SRT) for town halls and live events starting June 2026, offering a secure, low-latency alternative to RTMP with backup stream failover. This affects event producers using external encoders, requires no user impact or admin changes, and improves streaming reliability.

SRT will be available alongside Real‑Time Messaging Protocol (RTMP), the existing inbound streaming protocol commonly used with external encoders.
