Additionally, Microsoft will introduce new security reporting tools starting in June 2026, including end-user reporting for suspicious external users and a centralized Security Detection Report in the Teams admin center to surface messaging security detections such as impersonation attempts, malicious URLs, and weaponizable file types.
