M365 Changelog: Anonymous join policy

MC297030 – 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.

At launch, administrators will only be able to set the new policy using PowerShell. At a later date (no firm timeline as of today), the policy will be able to be controlled using the Teams admin center.  Microsoft will notify you when this happens via a future Message center communication. 

What you need to do to prepare:

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