Copilot will make SharePoint permission problems visible to everyone
A May 22 2026 webinar from Lightning Tools warned that Microsoft Copilot surfaces hidden SharePoint permissions across Microsoft 365. The session focused on how oversharing and stale access become immediately obvious once Copilot can query content. No new Microsoft product changes or release dates were announced. The discussion stayed at the level of awareness rather than specific fixes. Attendees were told that permission exposure will increase as more tenants activate Copilot features.
Before Copilot, permission mistakes stayed buried in site settings that only admins ever opened. Users could not easily discover documents they technically had access to, so the risk remained theoretical. Once Copilot is active, the same loose permissions turn into instant results in everyday searches. A former contractor or over-shared folder now appears in answers that reach leadership, turning a quiet governance gap into an obvious compliance failure.
Analysis
Stop planning the perfect full-tenant cleanup. Pick the 20-30 sites that hold HR, finance or client data and run a one-time external sharing and guest audit on those alone before anyone turns Copilot on.
