MC297030 (Updated) Anonymous join policy 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. We will notify you when this happens via a future Message center communication.
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.

MC279627 (Updated) Refreshed Microsoft Whiteboard client experience coming soon Updated November 05, 2021: We have updated the rollout timeline below. Thank you for your patience.
Microsoft Whiteboard is being updated to provide a new, unified experience across all devices, whether you’re on a large screen or a mobile phone. We’ve already shipped new, highly requested features to our web app, Android app and Teams clients, and there’s more on the way. As part of this new experience, we will also be updating our native applications on Windows 10, Surface Hub and iOS to provide a uniform experience across all devices.

This message is associated with Microsoft 365 Roadmap ID: 72196, 82093, and 82094.
[When this will happen:]
The mobile clients are fully updated and the Windows 10 client update has started, but it will now be complete by early December.

Updated November 18, 2021: During our gradual rollout of the new Whiteboard for Windows app, we learned that users love the new features but need some of the old ones back. We've also heard that some customers need more time before we automatically require transitioning new boards in OneDrive for Business (ODB) and more flexibility for rolling out the new unified Whiteboard for Windows app.
So today, we're doing two things:

We're pausing the Windows app rollout. Any users already upgraded will be automatically moved back to the previous version via automatic Store update. All the new Whiteboard features such as templates remain available in Teams, Web and mobile.
We're providing more time for you to decide how you want to opt into ODB storage and deploy the new unified client on Windows and Surface Hub.
What are the new dates and options?

For the client, we're addressing top requests for the new Windows app and will start the automatic store rollout in mid-February, completing by mid-March.
For the storage, we're giving you more time before transitioning storage to ODB. Default on will begin in late March and complete by mid-April.
For those who want the unified Windows client and/or ODB storage sooner, by mid-January we'll provide ways for you to deploy to your organization.

MC288630 (Updated) Exchange online archive–Automatic archive of mailbox items in Purges, Versions and Discovery Holds folders Updated November 11, 2021: We have updated the post for additional clarity and updated the timeline below. Thank you for your patience.
We are rolling out an update which will automatically move any mailbox items preserved in the “Purges”, “Versions”, and “Discovery Holds” folders in the primary mailbox to the archive mailbox daily. Customers will no longer be required to create separate policies for archiving email content in the “Recoverable Items” folders mentioned.

This change does not impact the “Deletions” folder which is also part of the “Recoverable items” folder.

MC296611 (Updated) Microsoft Defender for Office 365: Introducing Built-In-Protection We’re are introducing a powerful new default security preset called Built-in-Protection in Defender for Office 365.
Built-in-Protection is a third preset security policy (like the Standard and Strict preset policies), and is enabled by default for all new and existing customers. It will implement a version of Safe Links and Safe Attachments resulting in low impact on the end-user. It's low impact as the end user experience will not be changed - URL links will not be wrapped. However, it will implement delivery time file and URL detonation as well as time of click protection.
Microsoft 365 Roadmap ID 72208.
Timing: We will begin rolling out in mid-December and complete by late January.
Beginning in early November, you will be able to view the Built-in-Protection preset in the Defender for Office 365 portal and configure any exceptions required ahead of the policy enablement rollout that begins in mid-December.
Action: Review and assess impact to users in your organization.
