Microsoft is adding a new AI-powered security feature to Teams aimed at detecting phishing, scams, and identity theft by analyzing conversations, Bleeping Computer reports.
Instead of primarily checking for malicious links and files, the tool will be able to identify suspicious behavior in the messages themselves, Microsoft said. The feature will primarily be used for new contacts, as they pose a higher security risk.
The new security feature follows earlier warnings from Microsoft about attackers impersonating help desk staff in Teams to trick users into granting them remote access.
In a Microsoft 365 Message Center post (mirror), the company said, “During initial quality validation, detection may run in the background without showing warnings to users. After validation, users may see a warning when potential phishing is detected.”
According to Microsoft, no messages will be saved or used to train AI models. The tool will also be used solely for security purposes — not, for example, for surveillance or advertising.
The rollout will begin in early November 2026 and is expected to be generally available during the first half of December. IT teams do not have to configure the feature; it will be automatically enabled.
