Microsoft adds AI phishing detection to Teams starting November 2026
Microsoft will roll out AI-powered, context-aware phishing detection in Teams starting in early November 2026, with general availability expected worldwide by mid-December. The feature analyzes conversation context—particularly in external first-contact chats—to spot phishing, impersonation and social engineering attempts without relying solely on malicious links or files, and Microsoft says it won't retain message content for training or other purposes.
