Many organisations focus on licensing, pilots, and user training when planning Microsoft 365 Copilot adoption. Few spend enough time understanding what Copilot can already access. In this session, we will explore the hidden relationship between permissions, oversharing, sensitivity labels, governance controls, and AI generated responses. Learn how years of accumulated SharePoint and OneDrive permissions can become highly discoverable through natural language queries, and how administrators can identify and reduce risk before enabling Copilot at scale. Attendees will leave with a practical readiness framework, recommended review areas, and a security first approach to Copilot adoption.

For years, organisations have lived with broad access permissions because content was difficult to discover. Copilot changes that reality. This session demonstrates how AI can transform traditional oversharing issues into immediate information exposure risks. We will explore how permissions, inherited access, broad sharing groups, guest access, and legacy collaboration practices influence what Copilot can retrieve, summarise, and present to users. Attendees will learn practical techniques for identifying high risk content repositories and prioritising remediation efforts before large scale AI deployment.
