Microsoft said Teams would start using AI-based phishing detection in messages in early November 2026. It said the feature had first appeared in a Microsoft 365 Roadmap entry last week and was then described again in a Microsoft 365 Message Center update on Wednesday.
The company said the system would examine the context of a conversation rather than depend only on obvious markers such as links or files. It said the service would not keep customer message content for model training or other secondary uses.
Microsoft said the feature was aimed mainly at higher-risk messaging scenarios, including external first-contact chats. It also said administrators would not need to turn it on themselves.
The rollout was expected to run as a targeted release until mid-November. Microsoft said general availability worldwide was likely between early and mid-December.
