MC797116 Microsoft Stream: Less storage space consumed for Stream videos in Microsoft 365 Suite Changes to video and audio files from Stream will no longer take version snapshots. This means that any metadata changes made through Stream cannot be reverted to previous versions.

The following actions will no longer create a version in the file's version history:

Editing title or description from within Stream.

Adding or editing chapters, transcripts, captions, or interactivity.

Toggling media settings (show/hide about video, chapters, interactivity, comments, analytics, etc.).

Adding audio tracks.

The following actions will still create a version in the file's version history:

Editing column metadata in SharePoint document library for a video file.

Editing title or description from outside of Stream.

Replacing the file with a new different version of the file.

Other operations outside of the Stream app.

This change will happen by default, and there will not be a way to revert to the previous behavior where everything changed in Stream created versions.

This change will only stop new versions from being taken from Stream. To clean up existing versions of files or versions taken outside of Stream, the SharePoint team has a separate capability and new settings coming that will help clean up low value versions (see Roadmap ID 145802). Admins must complete this action for each site, and it will take approximately 30 days before the new version of the site is in effect.

MC805215 Microsoft Clipchamp: The Brand kit feature is rolling out with extended elements to Microsoft subscriptions You are receiving this message because users in your tenants have licenses which enable access to these capabilities.

User-created Brand kits can be stored in OneDrive or SharePoint.

Up to 300 of these brand elements can be stored with the Brand kit: videos, sound effects, music, images, backgrounds, and stickers.

The default state of this feature is on and all users with the specified licenses can access it.

MC889519 (Updated) Microsoft Defender for Office 365: Tenant Allow/Block List will support IPv6 allow and block entries Before this rollout: Admins cannot block or allow IPv6 addresses.

After this rollout, you can make IPv6 allow and block entries in these formats:

Colon-hexadecimal notation single IPv6 address (for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334)

Zero compression single IPv6 address (for example, 2001:db8::1)

Classless inter-domain routing (CIDR) IPv6 (for example, 2001:0db8::/32). The range supported is 1-128.

The IP block entry will drop any email sent from that IP at the edge, whereas the IP allow will just override the IP filtering, allowing the rest of the Defender for Office 365 stack to evaluate threats. IP block has a higher priority over IP allow entries.

Admins can create entries in the Defender portal or with the Microsoft PowerShell New-TenantAllowBlockListItems cmdlet (ListType parameter with value IP) without need for submissions.

This change will not impact any of your current Tenant Allow/Block List entries or your IPv4 entries in the hosted connection filter policy or enhanced filtering connection policy

Last used date support for IPv6 allow and block will be added soon.

Entry limits for IPv6:

Exchange Online Protection: The maximum number of allow entries is 500, and the maximum number of block entries is 500 (1000 entries in total).

Defender for Office 365 Plan 1: The maximum number of allow entries is 1000, and the maximum number of block entries is 1000 (2000 entries in total).

Defender for Office 365 Plan 2: The maximum number of allow entries is 5000, and the maximum number of block entries is 10000 (15000 entries in total).

Permissions:

The same existing set of permissions we have for Tenant Allow/Block List will also apply to this rollout.

Scheduling, setting up, and managing an event is not a simple task. Which is why we allow co-organizer to be added to the event so they can work alongside or on behalf of the organizer. So far co-organizers were able to set up event theming, manage registration, meeting options, view reports and more but were not able to edit event details like title, date/time, description, event group; nor publish or cancel event. Now they can! Co-organizer can edit event details, publish, and cancel the event like the organizer can. So once the co-organizer is added they will have full parity of experience as organizer and control/manage/edit event.

This chat will appear in their chat pane.

This means that all headings for both Text web part and titles in web parts will be as follow. Note: with this change we're not changing the default headings sizes for the Text web part:

Heading 2 will be 28

Heading 3 will be 24

Heading 4 will be 20

MC797116 Microsoft Stream: Less storage space consumed for Stream videos in Microsoft 365 Suite Video files tend to be very large and consume lots of space against your Microsoft OneDrive and Microsoft SharePoint storage quotas. Currently, when you make metadata changes such as title, description, transcripts, chapters, interactivity, thumbnails, media settings, etc. to files in Microsoft Stream, each of those changes cause new versions to be created. Each of these versions in Microsoft OneDrive and Microsoft SharePoint count the full file size towards consumed storage quota. Thus, for large video and audio files, these versions cause your storage consumption to quickly increase.

To prevent this, we are changing how Microsoft Stream handles versioning. Any changes made to metadata of files from Stream will stop making versions, thus preventing storage from increasing as rapidly as it has in the past.

This capability allows town hall attendees to watch the event instance within a particular website.

Embed for town hall introduces embeddable support for town hall engagement features on release. Attendees will have the same engagement feature access within the embed player as they do in client such as Q&A, Captions, Reactions and more.

To implement embed for town hall, organizers can access their town hall events unique embed code from the town hall scheduling template upon publish. Organizers can then take that code and inject it to their SharePoint or Microsoft 365 site as desired. On event start, attendees will be able to view and engage with the embed stream on the published site.

MC835648 (Updated) Announcing IPv6 Enablement for Accepted Domains To take advantage of IPv6 connectivity, please make sure that you and your partner's update network allow-lists to allow Exchange Online IPv6 endpoints in the same way it allow-lists IPv4.

The Exchange Online IPv6 endpoints can be found here: Microsoft 365 URLs and IP address ranges.

To opt a domain out of inbound IPv6 so traffic flowing to the domain remains IPv4-only, please use Disable-IPv6ForAcceptedDomain -Domain for each domain you want to opt out of IPv6 (Disable-IPv6ForAcceptedDomain (ExchangePowerShell) | Microsoft Learn).

IPv6 enablement may impact the source IP type used by Senders when connecting to Exchange Online, as the source and destination IP versions must match. For any IP Address-based Inbound connectors in Exchange Online that are referencing IPv4 addresses, you need to either:

Keep the sending server as IPv4.

Coordinate with the Sender so the Sender keeps connecting to your domain(s) via IPv4 or Opt your domain(s) out of IPv6

Change the IP based connector to certificate domain based connector.

This applies to both OnPremises type (From: Your organization's email server, To: Office 365) and Partner Type connectors (From: Partner organization, To: Office 365).

You can manage IPv6 for your Exchange Online Accepted Domains using the commands Enable-IPv6ForAcceptedDomain or Disable-IPv6ForAcceptedDomain.

Currently, you can check the status of your Accepted Domains with the Get-IPv6StatusForAcceptedDomain command. While some customers have already enabled IPv6, most will see it as disabled until October 16th.

After October 16, once IPv6 is enabled for your tenant, if you haven't explicitly set the IPv6 status for your Accepted Domains, the Get-IPv6StatusForAcceptedDomain command will reflect the new default behavior (enabled).

IMPORTANT: To ensure your preferred settings are applied, please use the Enable-IPv6ForAcceptedDomain or Disable-IPv6ForAcceptedDomain commands before October 16th, after which IPv6 will be enabled by default if you haven't explicitly set it.
