Summary
- Microsoft 365 Copilot Researcher is being modernized to use shared Copilot platform components, creating a more consistent experience across Microsoft 365.
- Several Researcher-specific UI controls and navigation areas will be retired, including report length control, Saved Prompts, History, Reports, Explore, and Recommended Prompts.
- Core Researcher capabilities for conducting research and generating reports will remain available; equivalent functions move to shared Copilot experiences such as prompt saving, conversation history, and Task Hub.
- No admin configuration changes or tenant opt-in are required, but admins should review the interface changes and update internal support materials.
- This affects Microsoft 365 Copilot licensed users who actively use Researcher-specific tabs and controls.
Microsoft is updating the Researcher experience within Microsoft 365 Copilot to use shared platform components between October and December 2026. Specific controls and tabs like report length settings and history views will be retired and replaced by broader Copilot features. Core research functions will stay available. Administrators should review the navigation changes and update internal help materials before the rollout finishes.
Administrator impact: No direct administrator action is required.
End user impact: Users must adapt to new navigation paths and shared prompt experiences as specific Researcher tabs and controls are retired.
Score rationale: This change causes interface modifications and requires internal documentation updates but involves no mandatory administrative configuration.
Microsoft 365 Copilot is updating Researcher to use shared Copilot components, retiring specific controls and tabs by December 30, 2026. Core research functions remain, but users must adapt to new navigation. No admin action is needed; admins should update documentation and inform users.
