Copilot Now Pulls Live Data From Outside Services Without Storing It
Federated connectors for Microsoft 365 Copilot are now generally available. They connect Copilot to popular third-party services and fetch data in real time over the Model Context Protocol (MCP), without storing or indexing it in Microsoft's services. They work in Researcher, Microsoft 365 Chat, and when editing with Copilot in Excel.
What changes
When your work is scattered across outside tools, Copilot can look up the latest version on the spot. Access runs under your own identity, so it's worth being deliberate about what you connect.Source →
