Microsoft Teams: New town hall event access policy

Updated July 15, 2025: We have updated the content. Thank you for your patience.

Before this rollout, Microsoft Teams has one admin policy to control event access for webinars and town halls. After this rollout, admins can control who can attend town halls in their organization with the new policy setting TownhallEventAttendeeAccess.

This message applies to Teams for Windows desktop, Teams for Mac desktop, Teams for the web, and Teams for iOS/Android.

This message is associated with Microsoft 365 Roadmap ID 483250.

When this will happen:

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

How this will affect your organization:

After this rollout, admins can control the event access for town hall created by their users with the new policy setting TownhallEventAttendeeAccess in the Teams admin center and Microsoft PowerShell. The policy has two new attributes: Everyone and Everyone in Organization including Guests:

• If Everyone is selected, town halls will not be restricted to a certain identity type; however, your organizers can still choose to restrict their town hall as they wish. This is the default setting.
• If Everyone in Organization including Guests is selected, town halls in your organization will only allow users in your organization and guest users to your tenant to attend. Town hall organizers may choose to further restrict their town halls but cannot invite users who are not part of their organization or who are not guests to attend.

If you have feedback on these attributes or have suggestions for new attributes, please send an email to [email protected]

What you need to do to prepare:

This rollout will happen automatically by the specified dates with no admin action required before the rollout. Review your current configuration to assess the impact on your organization. You may want to notify your users about this change and update any relevant documentation.

By default, TownhallEventAttendeeAccess will be set to Everyone. If you would like to change the default setting before the rollout begins, you can use this Microsoft PowerShell code:

Set-CsTeamsEventsPolicy -Identity Global -TownhallEventAttendeeAccess EveryoneInOrganizationAndGuests
