Add Microsoft 365 Copilot and agent experiences

Applies to: Developer

SharePoint Embedded agent experiences let your app answer questions over files stored in SharePoint Embedded containers. The recommended path is to use Microsoft Foundry Agent Service with a SharePoint knowledge source configured for SharePoint Embedded. For setup steps, see Set up SharePoint Embedded as a Foundry knowledge source.

Caution

The earlier SharePoint Embedded agent SDK (the React ChatEmbedded control) was deprecated in March 2026 and replaced by Microsoft Foundry Agent Service with a SharePoint knowledge source (preview) configured for SharePoint Embedded. Use the Foundry knowledge source for new work.

Test user experience

Sign in with a user who has a Microsoft 365 Copilot license when required. Upload supported files to a container, wait for indexing, open the chat, and ask questions the file content can answer. If answers omit expected files, check discoverability, supported file formats, app access, user access, scope selection, and indexing delay.
