Introduction
We’re introducing support for Microsoft Lists as a knowledge source for custom agents in SharePoint and OneDrive. These custom agents can now ground responses in a list stored on a SharePoint site or in your OneDrive.
When this will happen:
General Availability (Worldwide): We will begin rolling out in late March 2026 and expect to complete rollout by early May 2026.
How this affects your organization:
Who is affected:
- Site members (or people with edit permissions to the site) who create or edit custom agents in SharePoint and OneDrive.
- A Microsoft 365 Copilot license or the pay-as-you-go meter connected to SharePoint agents is required to use this feature.
What will happen:
- Users can configure a custom agent to use one Microsoft List as its knowledge source.
- Agents can:
- Answer questions using information stored in list items.
- Reference list item metadata in responses.
- Provide up-to-date responses based on list items the user has permission to access.
- In SharePoint, users can create an agent directly from a list by selecting AI actions > Create an agent from the command bar.
- While editing an agent, users can also select an individual list from the Sources tab, similar to selecting individual files.
- Important limitations:
- Agents currently support grounding on only one Microsoft List.
- Grounding on multiple lists, or combining a list with other content (such as files or pages), is not supported.
- If a list is added to an existing agent, all previous knowledge sources are removed, and the user is prompted to confirm before the change is applied.
- Agents configured with a site as the knowledge source will continue to ground only on the site’s Document Libraries and Pages library.
What you can do to prepare:
No action is required to prepare for this change.
We recommend that you:
- Inform users who create or manage agents about the new option to use Microsoft Lists as a knowledge source.
- Update internal guidance or help desk documentation if you provide instructions for creating custom agents in SharePoint.
