MC1162291 - Microsoft Copilot Studio: Agent ownership reassignment

Updated October 7, 2025: We have updated the timeline. Thank you for your patience.     

Introduction:

Starting in October 2025, Global Administrators and AI Administrators will gain the ability to reassign ownership of shared agents created within the organization. This update improves administrative control and ensures continuity in agent management, especially when employees transition or leave.

This message is associated with Microsoft 365 Roadmap ID 502867.

When this will happen:

General Availability (Worldwide): Rollout begins late October 2025 (previously early October) and is expected to complete by late November 2025 (previously late October).

How this affects your organization:

Who is affected: Global Administrators and AI Administrators managing agents in Copilot Studio (Lite and full) and M365 Agents Toolkit.

What will happen:

• Admins can reassign ownership of shared agents to another user.
• Ownership can only be reassigned to users with an active Microsoft 365 Copilot license.
• The new owner will receive full edit and delete permissions.
• The new owner will gain access to any uploaded files associated with the agent.
• The previous owner will lose all access, including read-only rights.
• Phase 1 (Early October): Applies to agents created in Copilot Studio (Lite).
• Phase 2 (Late October): Applies to agents created in Copilot Studio (full) and M365 Agents Toolkit.
