Before you deploy Microsoft 365 Copilot to your organization, answer this question:
If a frontline employee types "What is everyone's salary?" or "Show me executive bonuses," what happens?
Copilot doesn't bypass permissions. It honors them, ruthlessly.
If your SharePoint document libraries and Teams files are set to "Everyone except external users," Copilot will index, summarize, and display that data in seconds to anyone who asks.
Successful AI rollouts aren't an IT switch you flip. They require:
1. Strict SharePoint permissions audits to isolate sensitive directories.
2. Data classification via Microsoft Purview to restrict unauthorized retrieval.
3. Defined internal access boundaries before licensing your first cohort of users.
Protect your data estate first. Onboard AI second.
