Body (from Message Center)

Updated October 22, 2025: We have updated the content below. Thank you for your patience.

[Introduction]

We’re introducing Knowledge Agent, a built-in SharePoint capability that helps organizations prepare content for AI at scale. It unifies fragmented AI features into a single, context-aware interface that adapts to user roles and surfaces intelligent actions directly in the flow of work. This enhancement supports high-quality, trustworthy responses from Microsoft 365 Copilot and custom agents.

[When this will happen:]

Public Preview (Worldwide): Begins mid-September 2025; completes by late February 2026.

[How this affects your organization:]

Who is affected:

Users with a Microsoft 365 Copilot license on tenants opted into Knowledge Agent preview.
Admins managing SharePoint content and agents.

What will happen:

A floating button will appear in the lower-right corner of SharePoint surfaces, launching a context-aware menu with intelligent actions.
Role-based capabilities include:
- Content managers can structure, tag, and enrich content using smart metadata and AI recommendations.
- Site owners can identify stale pages, broken links, and content gaps.
- Content creators can generate pages and documents using natural language prompts.
- Collaborators and viewers can surface grounded insights via natural language chat.

Impact to SharePoint agents users:

Ready-made SharePoint site agents are now exclusively available to customers with Microsoft 365 Copilot licenses. These agents are no longer accessible through the Microsoft 365 Pay-As-You-Go (PAYG) billing model under the SharePoint agents meter.
PAYG customers can still create custom-built, no-code SharePoint agents using the same SharePoint agents meter, but they will not have access to the ready-made site agents unless they are Microsoft 365 Copilot licensed.
The SharePoint ribbon icon has changed from the Copilot logo to a hexagon to indicate Knowledge Agent-enabled sites.
Agent creation remains available via:
- Site homepage
- Agent chat pane
- AI actions menu in the command bar of a document library
- Content menu of selected file(s) in a document library

[What you can do to prepare:]

Knowledge Agent Public Preview begins September 18, 2025 on a tenant opt-in basis to users with a Microsoft 365 Copilot license.
