Microsoft Teams Adds Context-Aware AI Detection for Phishing Chats

Microsoft is adding AI-powered, context-aware phishing detection to Microsoft Teams, designed to flag suspicious behavior in conversations, including messages without malicious links or files. The feature focuses mainly on chats with new external contacts and can warn users when activity appears harmful. Microsoft’s support page describes the detection as available worldwide on mobile, desktop and web, while a recent Microsoft 365 roadmap listing identifies the feature as in development and gives a November 2026 general-availability target. Microsoft’s support information and rollout schedule therefore appear to reflect different stages of the release.
