Retirement of the isBroadcast property for Teams Live Events in Microsoft Graph

Originally posted by Microsoft Feb 3, 2026 Uncategorized 0 Comments

The isBroadcast property for creating Teams Live Events via Microsoft Graph will be retired by June 30, 2026. Developers must transition to Virtual Event APIs for Webinars and Town Halls. Existing events remain unaffected; migration and testing are advised before retirement.

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

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.
