[What and Why]<\/b><\/p>\n

Microsoft Teams is updating the port and domain requirements for Real-Time Messaging Protocol (RTMP)-In, which enables organizers to stream content into meetings, webinars, and town halls using external hardware or software encoders. This change improves reliability and scalability for Teams streaming scenarios.<\/p>\n

[Rollout Schedule]<\/b><\/p>\n

    \n
  • General Availability (Worldwide)<\/b>: We will begin rolling out in early July 2026<\/b> and expect to complete by late July 2026<\/b>.<\/li>\n<\/ul>\n

    [Impact on Your Organization]<\/b><\/p>\n

    Who is affected<\/i><\/p>\n

      \n
    • Admins managing Microsoft Teams meetings, webinars, and town halls<\/li>\n
    • Event organizers who use RTMP-In with external encoders<\/li>\n<\/ul>\n

      Platforms\/Services<\/i><\/p>\n

        \n
      • Microsoft Teams (meetings, webinars, and town halls)<\/li>\n<\/ul>\n

        What will happen<\/i><\/p>\n

          \n
        • New meetings, webinars, and town halls that use RTMP-In will require updated network access.<\/li>\n
        • Admins must allow the required ports and domain endpoints for RTMP-In streaming.<\/li>\n
        • Existing meetings, webinars, and town halls already configured with RTMP-In will continue to function through the end of 2026.<\/li>\n
        • RTMP-In continues to allow organizers to stream content into Teams from external hardware or software encoders.<\/li>\n
        • Without these updates, organizers may be unable to create or stream RTMP-In events, and newly created events may fail after mid-July 2026<\/b>.<\/li>\n<\/ul>\n

          Required network endpoints:<\/b><\/p>\n
