Microsoft Teams

Updated September 1, 2026: We have updated the timeline. Thank you for your patience. [Introduction] We’re introducing a private chat feature for organizers, co-organizers, and presenters in structured meetings and webinars in Microsoft Teams. This separate chat enhances collaboration by allowing key participants to communicate privately before, during, and after the event, without involving attendees. Additionally, we are unifying backroom chat behavior in town halls to ensure consistent functionality across all structured meetings. Currently, backroom chat behavior varies depending on whether streaming chat is enabled for town halls and whether the organizer has a Teams Premium license. This update removes that inconsistency.This message is associated with Roadmap ID 392328 and applies to Teams for Windows desktop, Teams for Mac desktop, Teams for the web, Teams for iOS/Android, MTR-W
