(Updated) Microsoft 365 admin center: Agent Registry consolidates duplicate agent entries and adds version history

Updated September 29, 2026: We have updated the timeline. Thank you for your patience. 

[What and why]

We're improving the Agent Registry experience in the Microsoft 365 admin center by consolidating duplicate entries for the same agent into a single record. Previously, the same agent could appear multiple times when published across different scopes or when multiple published versions existed.

This update simplifies agent governance, provides a clearer inventory of deployed agents, and makes it easier for admins to manage agent lifecycle and version history from a single location. All versions of an agent will be accessible from the agent details flyout while governance actions continue to apply across the entire agent.

[Rollout schedule]

• Worldwide: Beginning in mid-September 2026 and expected to complete in mid-October 2026 (previously late September)

[Impact on your organization]

Who is affected

• Global Administrators
• Global Readers
• AI Administrators
• Organizations using the Agent Registry

Platforms and services

• Microsoft 365 admin center
• Agent Registry

What will happen

• Each agent will appear only once in the Agent Registry.
• Agents that previously appeared as multiple entries due to different publishing scopes or published versions will be consolidated into a single entry.
• The Registry list will display the most recently published organizational version by default.
• Selecting an agent will open an agent details flyout that includes a version selector.
• The version selector will display available published versions and any in-progress draft versions where applicable. Selecting a version will update the agent details shown in the flyout.
• Governance actions, such as Block, will continue to apply to the entire agent across all versions.
• Total agent counts in the Agent Registry may decrease because duplicate entries are being consolidated. No agents are being removed.
• Reports, dashboards, exports, and custom processes that relied on previous per-entry counts may show different totals after rollout.
• Registry exports will include options for exporting agents and their associated versions.
• This change is enabled by default and requires no configuration.

[Action required and recommendations]

No action is required.

We recommend that administrators:

• Inform governance and operations teams that Agent Registry counts may decrease as duplicate entries are consolidated.
• Review internal reports, dashboards, scripts, and processes that depend on Agent Registry counts or export data.
• Update internal documentation and training materials to reflect the new version selector experience in the agent details flyout.
• Validate any downstream reporting that uses Agent Registry export data after rollout is complete.
