Why this score?
AI Confidence
HIGH
Enough detail is available to trust this assessment.
Assessment Reasoning
Timeline for general availability has shifted later, reducing urgency but still relevant for admins tracking Teams webinar and townhall capabilities. Feature extends co-organizer permissions to allow full event editing and publishing, which may require updated internal processes and communication. No technical preparation is specified, so implementation effort and admin impact remain moderate. Users may see workflow improvement but minimal disruption.

📢 Official Microsoft Message Center Announcement

(Updated) Co-organizer experience updates in Teams Webinars and Townhalls
Message ID: MC688109 (Updated)

Updated September 2, 2026: We have updated the timeline. Thank you for your patience.

Scheduling, setting up, and managing an event is not a simple task. Which is why we allow co-organizer to be added to the event so they can work alongside or on behalf of the organizer. So far co-organizers were able to set up event theming, manage registration, meeting options, view reports and more but were not able to edit event details like title, date/time, description, event group; nor publish or cancel event. Now they can! Co-organizer can edit event details, publish, and cancel the event like the organizer can. So once the co-organizer is added they will have full parity of experience as organizer and control/manage/edit event. 

This message is associated with Microsoft 365 Roadmap ID 168524

[When this will happen:]

Targeted release: We will begin rolling out mid-January 2025 (previously early January) and expect to complete by mid-January 2025 (previously mid-December).

General Availability (Worldwide, GCC): We will begin rolling out mid-June 2026 (previously early March) and expect to complete by early October 2026 (previously end of August). 

The co-organizer experience update will go live with the GA of the Teams Events app (MC1227087). Both existing flow and new flows in the Teams Events app will have the capabilities for co-organizer parity with organizer. 

[How this will affect your organization:]

When co-organizer opens the event scheduling page, they should have the ability to edit the details page, publish, and cancel the event. 

[What you need to do to prepare:]

Nothing required to prepare.
