Microsoft Adds Teams Reporting Tools to Counter AI Deepfake and Meeting Fraud

Microsoft is rolling out a "Report a concern" feature in Microsoft Teams that lets meeting participants flag suspected phishing, impersonation, scams, social engineering, and other suspicious behavior tied to meetings or meeting chat. Reports will be surfaced to defenders through the Teams admin center and Microsoft Defender portal, where security teams can review meeting metadata and limited contextual information as they investigate possible abuse. Microsoft is also adding controls to detect external meeting bots and improve organizer visibility into unauthorized AI assistants joining meetings, with the feature enabled by default as part of a broader push to harden collaboration platforms against fraud.

The move follows Microsoft's warning that AI-powered deception is accelerating fraud operations, including deepfake participants, voice cloning, and other impersonation tactics that exploit trust in digital communications. Separate user reporting has also highlighted how Microsoft security workflows can create confusion for administrators and employees, particularly when phishing-reporting actions in Outlook appear in security tooling as user interaction with a malicious message. Together, the updates show Microsoft expanding in-product reporting and investigation capabilities while organizations contend with increasingly convincing AI-enabled scams across email and meetings.
