Microsoft Teams: Impersonation Protection for Teams meetings
Microsoft Teams will add impersonation protection warnings for meetings, automatically detecting and surfacing risk indicators when suspicious participant identities are detected. This is a new security feature with no required admin action.
Microsoft's description
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.
