SharePoint List Support in Agent Builder

Agents built in Microsoft 365 Copilot Agent Builder can now use a SharePoint list as a knowledge source, so they answer from structured data.

  • Point an agent at a SharePoint list and it answers questions from the rows in that list, alongside its other knowledge sources
  • One list per agent, up to 20,000 items
  • List attachments and lookup columns are not supported yet
  • Windows and web, generally available

Best for

An agent that has to answer from a table your team already maintains, like a product list or an approval log.

When to use it

The answers live in rows and columns rather than in documents.

Who benefits

Anyone building Copilot agents in Agent Builder, no code required.
