Microsoft Teams: Phishing Detection in Teams Messaging

Summary

Microsoft Teams is introducing AI-powered phishing detection that uses conversation context to identify phishing and social engineering in higher-risk messaging scenarios, primarily external first-contact chats. Additional protection may apply in certain regions or scenarios. The capability is used only for security protection, and users may see warnings when suspicious activity is detected.
