Manage who can upload advanced agents and plugins

🚨

Major Update: This post contains a significant change that may impact your organisation.

What and Why

To help organizations manage the deployment of advanced Copilot extensibility scenarios, we are introducing a new admin control that determines who can upload advanced agents and plugins. This enhancement strengthens enterprise governance and manageability by allowing administrators to limit advanced-package uploads to specific users or Microsoft Entra ID groups while maintaining flexibility for organizations that want broader access. This aligns with Microsoft's Enterprise-ready AI commitment by giving admins greater control over how advanced AI-powered solutions are introduced into their environments.

Rollout Schedule

  • General Availability (Worldwide): Rollout begins October 12, 2026.
  • Expected completion by the end of October 2026.

Impact on Your Organization

  • Microsoft 365 administrators responsible for managing Copilot agents and plugins.

  • Users who create or upload advanced agents and plugins after this feature becomes available.
