(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)

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.
