Only by leaving the meeting. When the organiser starts recording or transcription, Teams shows a consent message. You can accept and stay, or decline and be disconnected, but you cannot opt out while staying in the call. The same applies to people from inside and outside your organisation.
- Copilot meeting recaps are built from the transcript, so no transcript means no recap.
- Do not record or transcribe meetings where confidential information will come up.

Can I make Copilot forget Sensitive Information?
Not cleanly. You can delete chats and saved memories, but you cannot make Copilot forget one item from a meeting transcript or a document it has already processed. The safest approach is prevention: do not start transcription or share files when sensitive information could come up, and be open about it if it happens.
What is a Microsoft 365 tenant?
A Microsoft 365 tenant is your organisation's own private space in the Microsoft cloud. Your email, Teams, files and Microsoft 365 Copilot all run inside it, and your data stays in that space instead of being pooled with other customers. That is why the work version of Copilot is safer than a consumer chatbot.
Is Copilot Chat-Only Mode Safer for Sensitive Documents?
No, the mode makes no difference. Whether you use chat only or agent mode, Copilot reads the document once you give it access. The real decision is whether that document should go into Copilot at all, so check your organisation's rules on which data classifications are allowed before you open it with AI.
