M365 Changelog: Anonymous join policy

MC297030 – Updated November 18, 2021: Microsoft has updated the content below with additional details. Thank you for your patience.

Administrators will be able to control the ability for anonymous users to join a Microsoft Teams meeting using a new per-organizer policy.

This message is associated with Microsoft 365 Roadmap ID 87503.

When this will happen:

Microsoft will begin rolling this out in mid-November and expected to complete in late November.

How this will affect your organization:

This policy will provide administrators more granular control by enabling them to allow specific users, or groups of users to admit anonymous users into meetings they organize.

The new per-organizer policy is controlled using the -AllowAnonymousUsersToJoinMeeting parameter in Set-CsTeamsMeetingPolicy This comes with Teams PowerShell version 2.6.0 and later.

To assist with the transition from the old tenant-wide setting to the new policy, there are two phases to this rollout.

• Phase 1: The new policy has rolled-out and can be set by administrators. During this phase, the old tenant-wide setting will still exist and can be changed by administrators. Administrators will need to understand how the tenant-wide setting and the policy work together.
• Phase 2: The old tenant-wide setting will be retired. The new per-organizer policy will fully control anonymous join.

You learn read more about the co-existence of the setting & meeting policies during Phase 1 here.

What you need to do to prepare:

Please consider updating policies for your users and updating your internal documentation and training guides.
