Microsoft Teams is introducing a new security feature to alert users of potential brand impersonation in Teams Chat, especially during initial contact from external domains. Rollout begins late October 2024 for Targeted Release and mid-November 2024 for General Availability, completing by mid-February 2025. This feature will be enabled by default with no admin configuration needed.
