Impersonation protection for Teams meetings helps users identify potentially deceptive participants and meeting organizers. When Teams detects a potential impersonation attempt, it surfaces warnings and risk indicators to help users recognize suspicious identities and make more informed decisions when joining or participating in a meeting.
[Rollout Schedule:]
General Availability (Worldwide): We will begin rolling out in mid-December 2026 and expect to complete by late December 2026.
