Question

A compliance officer is concerned that Microsoft 365 Copilot might expose confidential documents to employees who should not see them. A department manager asks whether enabling Copilot will let staff read files they currently cannot access. What should you tell the manager about how Copilot accesses organizational data?

Accepted Answer

Copilot only returns content the requesting user already has permission to access, because it grounds responses on Microsoft Graph while enforcing existing access controls.

Answer

Copilot indexes all tenant content with elevated service permissions, so any user can retrieve any file through a prompt.

Answer

Copilot bypasses SharePoint permissions but applies sensitivity labels afterward to decide what a user can see.

Answer

Copilot grants users read access to any document referenced in a response for the duration of the chat session.
