Microsoft Copilot (Microsoft 365): [Copilot Extensibility] Connector Metadata Enrichment for Custom Copilot Connectors Beta
Data as of 2 hours ago (9 September 2026)
Description
We’re introducing new options that allow admins and developers to enrich their custom Copilot connectors and its schema properties with descriptive metadata. With this update, you can now: * Provide richer context about the connection and its schema properties to Copilot’s LLM, enabling more accurate and relevant responses. Add alternate names, data source categories, common actions to your connector and description for schema properties. * Improve search and chat quality by helping Copilot better understand the semantics and purpose of your data.
Change history
Added to the roadmap 25 July 2025. Tracked here since 1 September 2026. Earliest target we recorded: September 2025 (since tracked — Microsoft may have moved it before we started watching).
