(Updated) Microsoft 365 admin center: Organizational Messages now support Action Segments for Microsoft 365 Copilot [MC1189666]

Message ID: MC1189666 (Updated)

Updated April 16, 2026: We have updated the timeline. Thank you for your patience. 

[Introduction]

Action Segments empower IT admins to target Organizational Messages using dynamic, pre-defined usage segments. This enhancement helps admins deliver more relevant communications based on user activity. For the Public Preview, there are two Action Segments available: Inactive Microsoft 365 Copilot Users and Inactive Microsoft 365 Copilot Users in Teams.

This message is associated with Microsoft 365 Roadmap ID 503563.

[When this will happen]

• General Availability (Worldwide): Rollout begins in late April 2026 (previously mid-April) and is expected to complete by late May 2026 (previously mid-May).
