MC999446 - Microsoft Teams Events: Attendees and presenters no longer receive an email when an attendee list is updated

Updated May 8, 2025: We have updated the rollout timeline below. Thank you for your patience.

For Microsoft Teams town halls and webinars, presenters and attendees will no longer receive an updated email every time a presenter is added or removed or when incremental changes are made to the participants list for the event.

When this will happen:

General Availability (Worldwide, GCC, GCC High): We will begin rolling out late May 2025 and expect to complete by late June 2025.

How this will affect your organization:

Teams attendees and event participants no longer receive an email when the attendee list is updated.

What you need to do to prepare:

This rollout will happen automatically with no admin action required. You may want to notify your users about this change and update any relevant documentation as appropriate.
