Microsoft Teams to add certified third-party deepfake detection for synthetic audio and video in meetings, plus built-in impersonation warnings; general availability planned for November
Microsoft has added two Teams meeting features to the Microsoft 365 Roadmap, BleepingComputer reported on 8 October 2026. The first lets organisations plug in certified third-party tools that analyse meeting audio and video for signs of synthetic or manipulated media and send detection signals into Teams, which will surface them in the meeting with related controls. The second, impersonation protection, warns users and shows risk indicators when Teams detects that a meeting organiser or participant may be pretending to be someone else. Both are in development, with a worldwide rollout and general availability planned for November. They follow other Teams anti-abuse changes: admins locking out external users through the Defender portal, blurring of QR codes from external senders, a meeting policy that blocks identified external bots, and reporting of suspicious guest invitations from November. The deepfake feature depends on buying a supported third-party provider; Microsoft has not named providers or prices. Source: BleepingComputer, citing Microsoft 365 Roadmap entries.
