Teams Cross Cloud Guest Access General Availability
[MC672521 · Published Aug 31, 2023]: Teams Cross Cloud Guest Access (CCGA) extends existing Guest Access functionality allowing a user to participate in rich collaboration experiences in teams, channels, documents, and Teams meetings between tenants across Microsoft clouds. Guests are able to participate in a full collaboration experience including audio/video, screen share, file share, and both 1:1 and 1:many chats. These features are enabled through the Azure Active Directory B2B feature and the newly released Cross Tenant Access Settings. When combined tenants can enable trust between tenants and between Microsoft clouds.
This message is associated with Microsoft 365 Roadmap ID 145459.
When this will happen:
Standard Release: This feature will be available in late September 2023.
How this will affect your organization:
This change only impacts your organization if there are configured cross-tenant access settings between tenants in different Microsoft clouds and Teams Guest Access is enabled. Once configured users will be able to invite new guests and add guests from another cloud to Teams using the same procedures they use today for guests in the same cloud.
Any compliance controls, identity governance or other management tooling used today to manage same cloud B2B Guests may need to be reviewed, updated or extended to include support for B2B guests from another Microsoft cloud. Azure Active Directory Identity Governance has already been updated to fully support management of B2B guest from other Microsoft clouds.
What you need to do to prepare:
If you are interested in using this feature, familiarize yourself with Azure Active Directory B2B, Cross Tenant Access Settings, Identity Governance, and Teams Guest Access.

Generate unique join links for external presenters so they can easily join events
[MC675281 · Published Sep 14, 2023]: Organizers can set up events and effortlessly add external presenters, who will receive exclusive Teams join links. These links enable external presenters to directly enter the event, eliminating the need for organizers to manually admit them from the event lobby or modify their event role during the session. This creates a hassle-free event experience for organizers and presenters!
External Presenters are considered people outside of your organization, including guests (AAD/B2B/non-AAD), federated, unfederated, and anonymous users (non-AAD).
This feature is available for webinars only. This is not a Teams Premium feature.

Power Platform – Announcing General Availability of Access Check to view all users who have access to a record
[MC675134 · Published Sep 13, 2023] We are preparing an update that will allow record owners to view all users who have access to their record(s). This update is expected to be released by the end of September.
What actions do I need to take to prepare?
This feature will be enabled by default in your environment after the release of the update by the following two settings that will be introduced. You can reset these settings to better fit your business needs:
- IsAccessCheckerAllUsersEnabled: This allows the admin to see who has access to the record.
- IsAccessCheckerNonAdminAllUsersEnabled: This allows the admin, owner of the record, and users who have access to the record to see who has access.

Ability to change retention period on labels set to start retention based on “When items were labeled”
[MC674977 · Published Sep 12, 2023]: Previously, admins could not change the retention period set on existing labels configured to start retention from when items were labeled. This feature will remove this restriction, and the resulting behavior will be consistent with other retention label types.
This message is associated with Microsoft 365 Roadmap ID 153651
When this will happen:
Rollout will begin in early October 2023 and is expected to be complete by mid-Jan 2024.
How this will affect your organization: The next time you edit retention labels set to start retention based on when items were labeled, you should see the ability to update the retention period as below:

This change will now provide greater control over retention labels set to start retention from when items were labeled and ensure the user experience is consistent with other retention label types.
You will also have the ability to update the retention period via cmdlets just like in other retention label types.
What you need to do to prepare:
There’s no need for you to do anything to receive this change. However, we recommend reviewing your existing retention labels set to start retention from when items were labeled and update their retention period if required.
