Not reliably, so do not depend on it. Some organisations set up data loss prevention policies that can block or flag sensitive information, but there is no general alert that catches every name or personal detail you paste in. Checking what you share with Copilot is always your own responsibility.
- Remove or replace names and personal details before you paste text in.
- Ask your IT team which data protection policies are switched on in your organisation.

Can I refuse to be recorded or transcribed in a Teams meeting?
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.
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.
