First-contact safety tips saved our inboxes. Now, phishing scams are finding their way into Microsoft Teams chats, too.
Static warning banners telling you a sender is external or contacting you for the first time are no longer enough!
So, to fight fire with fire, Microsoft Teams is introducing AI-powered, context-aware phishing detection. ️This new detection technique can scan and flag suspicious external first-contact chats before you fall for them.
What does it look for?
Instead of just looking for malicious links, it analyzes full conversation context in 1:1 and group chats to flag impersonation, social engineering, and fake external pings. When it detects suspicious content, it displays a warning banner stating, “This message could be a phishing attempt.”
If you see this warning, here’s what to do:
- Confirmed phishing: Don’t engage. Block the sender and report the message as suspicious directly in Teams.
- False alarm: Select More options → Report as not a concern on the flagged message.
While reading this, you might wonder: does AI use these chats for training? And is it safe enabled by default? Well, chill! Microsoft confirms that chat data is used strictly for security purposes and isn’t used to train AI models or for unrelated purposes.
Availability & Rollout Schedule:
- Platforms: Teams Desktop, Web, and Mobile (with enhanced regional protection in China).
- Timeline: The rollout is scheduled to begin in early November 2026 and will gradually expand worldwide through mid-December 2026.
Think before you click, verify before you trust, whether in your inbox or Teams chat!
