SharePoint Oversharing
When SharePoint content has overly broad permissions or sharing links, exposing sensitive data that Copilot can then surface.
SharePoint oversharing occurs when files or sites carry permissions broader than necessary—such as “Anyone with the link” sharing or site-wide access granted to large groups—leaving sensitive content readable by far more users than intended. Because Microsoft 365 Copilot respects existing permissions and surfaces content from across the tenant, oversharing directly shapes what Copilot can retrieve in responses.
The key exam distinction is prevention versus mitigation: Data Access Governance reports identify sites and files with overly broad access so administrators can remediate before deploying Copilot, while Restricted Content Discovery excludes specific sites from Copilot and search results. Remediating permissions is the preferred long-term control; Restricted Content Discovery is not a substitute for correcting underlying access.
