Microsoft's description
Users can now report suspicious external users directly within Teams, alongside existing block actions. Reports are surfaced in the Teams admin center, giving admins visibility into potentially risky interactions and enabling them to investigate and take appropriate actions. This enhancement helps organizations respond faster to phishing, impersonation, and other external threats while leveraging end-user signals as an additional layer of protection.
