The permissions model within your Microsoft 365 tenant can help ensure that data won't unintentionally leak between users, groups, and tenants. Microsoft 365 Copilot presents only data that each individual can access using the same underlying controls for data access used in other Microsoft 365 services. Semantic Index for Copilot honors the user identity-based access boundary so that the grounding process only accesses content that the current user is authorized to access.
