💡 Our Technical Review in summary
Summary
- Microsoft is retiring the
isBroadcastproperty within the Microsoft GraphonlineMeetingresource, which is currently used to programmatically create Teams Live Events. - This retirement is part of a transition toward the more modern Virtual Event APIs, which support advanced features for Webinars and Town Halls.
- The
isBroadcastproperty will be removed from the Microsoft Graph beta endpoint on March 31, 2026, and from the v1.0 endpoint on June 30, 2026.
Impact
- Developers & Automation: Any custom applications, scripts, or third-party integrations that use Microsoft Graph to create Teams Live Events via the
isBroadcastproperty will fail after the retirement dates. - Functional Change: Programmatic creation of new Teams Live Events will no longer be supported through the legacy
onlineMeetingAPI. Organizations must adopt thevirtualEventTownhallorvirtualEventWebinarresources instead. - Existing Events: Any Teams Live Events scheduled before the June 30, 2026, deadline will continue to function and conclude as expected.
- General Users: There is no immediate impact on users manually creating events through the Teams client; this change specifically targets API-driven workflows.
Action Required
- Audit Integrations: Identify all internal apps, PowerShell scripts, or workflow automations that interact with the Microsoft Graph
onlineMeetingendpoint. - Update Codebase: Transition development from
isBroadcastto the Virtual Event APIs:- Use
virtualEventTownhallfor large-scale broadcast scenarios (replacing Live Events). - Use
virtualEventWebinarfor structured events requiring registration.
- Use
- Timeline for Testing: Complete migration and testing on the beta endpoint before March 31, 2026, to ensure no disruption when the v1.0 endpoint is updated in June 2026.
- Update Documentation: Revise internal technical documentation and notify application owners or developers responsible for maintaining Microsoft 365 integrations.

[Introduction]
We’re retiring the isBroadcast property used to create Teams Live Events through Microsoft Graph. This change aligns with our investment in the Virtual Event APIs, which offer richer capabilities for Webinars and Town Halls, including improved registration, attendee management, presenter configuration, and reporting. These APIs provide more modern, flexible, and scalable options for organizations managing large virtual events.
[When this will happen]
- March 31, 2026: isBroadcast will be removed from the Microsoft Graph beta endpoint
- June 30, 2026: isBroadcast will be removed from the Microsoft Graph v1.0 endpoint
[How this affects your organization]
Who is affected: Organizations and developers who use the Microsoft Graph onlineMeeting resource with the isBroadcast property to create Teams Live Events programmatically.
What will happen:
- The isBroadcast property will no longer be available in Microsoft Graph after the dates listed above.
- Attempts to create Teams Live Events using isBroadcast will fail.
- Programmatic creation of new Teams Live Events through Microsoft Graph will no longer be supported.
- Developers should transition to the Virtual Event APIs, which support Webinar and Town Hall scenarios.
- Existing Teams Live Events scheduled before the retirement date will continue to function normally.
[What you can do to prepare]
If your apps, scripts, or workflows use isBroadcast, you should:
- Review updated API documentation and migration guidance.
- Migrate to the Virtual Event APIs:
- virtualEventWebinar for Webinars
- virtualEventTownhall for Town Halls
- Test updated workflows before the retirement dates.
- Update any internal documentation and notify app owners or developers who maintain integrations.
- If your organization does not programmatically create Teams Live Events using Microsoft Graph, no action is required.
