impersonation protection

Impersonation protection covers the safeguards Microsoft is building into its collaboration and communication services to flag people who may not be who they claim to be. The tagged content centers on Microsoft Teams, where a planned feature called Impersonation Protection for Teams meetings will warn organizers and attendees when a participant on screen or the sender of a meeting invite may be misrepresenting their identity. Listed on the Microsoft 365 Roadmap with a November 2026 target, the capability is still in development rather than available today, so discussion here tracks roadmap news, rollout expectations, and what the warning means for meeting security.
