2025-12-05T11:10:13.19+00:00 In Copilot Studio, a 'knowledge source' refers to a configured data input (or data connection) for an agent: for example — a public website, uploaded documents (files), a SharePoint site or folder, a database in Microsoft Dataverse, or other enterprise data via connectors.
