Microsoft 365 Message Center announcement MC1550540.

MS Message Center's Summary

Microsoft is updating Copilot Workspaces to replace manual agent selection with an automated agentic chat model beginning December 2026. Users will no longer select individual researcher or analyst options manually but instead rely on natural language prompts to trigger skills automatically. Administrators should update internal guidance and inform users that core capabilities remain accessible through the main Copilot app.

Administrator impact
No direct administrator action is required.
End user impact
Users will interact with Copilot Workspaces through natural language chat rather than manually selecting specific functional agents.
Importance
3/10: This is a feature update affecting user workflows in preview, requiring awareness and documentation updates but no technical configuration.

Microsoft Summary

Microsoft 365 Copilot Workspaces will replace standalone agent selection (Researcher, Analyst, Designer) with an agentic chat that applies skills based on user requests.

[What and why] Microsoft 365 Copilot Workspaces (formerly Copilot Notebooks) is moving to an agentic chat experience. As part of this change, Researcher, Analyst, and Designer will no longer be available as standalone agent options within Copilot Workspaces. Instead of selecting or switching between agents, users can describe what they need in plain language. Copilot will automatically apply the appropriate research, analysis, or design skills based on the request and the workspace content. This change simplifies the user experience while preserving existing capabilities. Researcher, Analyst, and Designer will remain available as separate agents in the Microsoft 365 Copilot app for users who prefer working with a specific agent. [Rollout schedule] Frontier preview: Rollout is planned to begin in December 2026 . The completion date has not yet been determined. Rollout dates for general availability are still being finalized. We will provide additional information when available.
