Microsoft 365 Roadmap
Agent Builder now supports using a SharePoint list as a knowledge source for agents in Microsoft 365 Copilot. Makers can ground an agent in structured list data so users can ask questions and get responses based on information stored in a selected SharePoint list. For this release, each agent can reference one SharePoint list with up to 20,000 items, alongside other knowledge source types. Support for list attachments and lookup columns is not yet available.
