When you use Microsoft 365 Copilot Chat without a Microsoft 365 Copilot license, Copilot Chat operates in a “general” mode rather than a Microsoft Graph-grounded work mode. In this configuration, Copilot does not have the entitlement to access and reason over your organization’s protected Microsoft 365 content (such as SharePoint sites, OneDrive files, Outlook mail, Teams messages, or other tenant resources). It also does not connect directly to your organization’s internal databases unless separate, explicitly configured integrations exist.

Instead, Copilot relies on three primary sources to generate a response: (1) the prompt context you provide in the current request (what you ask, plus any text you paste), (2) the conversation history within the current chat thread to maintain continuity, and (3) internet search data (when web grounding is available) to supplement general knowledge with up-to-date public information.

Therefore, the correct selections are C (prompt context), E (internet search data), and F (conversation history), while organizational Microsoft 365 data and Teams chat data are not used without the Copilot license.
