Semantic search now considers body, chat and transcription of recent meetings. Understand discovery, access, retention, and governance.
Direct answer
Microsoft 365 Copilot now finds meetings by themes and keywords present in the body of the invitation, in chat messages and in transcripts. According to the September 23, 2026 release notes, the transcript search considers meetings from the previous two months. The new feature reduces the time to retrieve decisions and context, but expands the discovery surface of sensitive conversations. The organization must review permissions, recording and transcription policies, retention, labeling, and participant expectations before treating the resource as corporate memory.
Semantic search recovers scattered context
The same decision can be made in the invitation, in the chat or in the transcribed speech. Querying these surfaces together reduces the reconstruction cost.
Permissions remain the perimeter
The assistant should respect user access, but broad permissions or outdated groups continue to expose content to the wrong people.
Transcription changes the expectation of the meeting
When speech becomes searchable, participants need to know what will be recorded, for how long, and for what organizational purposes.
Result found is not official minutes
A relevant passage may be incomplete or contradict the final decision. The answer must lead to the original source and context.
Nexus Reading
Define which meetings can be transcribed, keep access to a minimum, publish formal decisions, and treat AI search as navigation, not a substitute for the official record.
