MC ID MC Title Old Value New Value MC Action required by
MC1097225 (Updated) Entra ID: Upcoming changes to support passkey profiles in the authentication methods policy (preview) After this rollout, you'll be able to apply different passkey configurations per user group. For example, you will be able to:

Allow the use of specific FIDO2 security key models for user group A

Allow the use of passkeys in Microsoft Authenticator for user group B

Important: If your organization opts-in to the new admin UX and modifies the Default passkey profile, the new schema will take effect. If you continue using Graph API or third-party tools to modify the policy, the schema will not change until General Availability.

These new settings will be available at Microsoft 365 admin center > Home > Security > Authentication methods > Passkey (FIDO2) settings:

As part of this update in November 2025, if Enforce attestation is disabled, we will start accepting security key or passkey providers using the following attestation statements:

"none"

"tpm"

"packed" (AttCA type only)

Custom attestation formats ≤ 32 characters

This will allow a wider range of security keys and passkey providers to be accepted for registration and authentication in Microsoft Entra ID. To compare this upcoming update with the current behavior, refer to Microsoft Entra ID attestation for FIDO2 security key vendors

After this rollout, you'll be able to apply different passkey configurations per user group. For example, you will be able to:

Allow the use of specific FIDO2 security key models for user group A

Allow the use of passkeys in Microsoft Authenticator for user group B

Important: If your organization opts-in to the new admin UX, a Default passkey profile will automatically be populated with your existing policy configurations. Once you modify and save the Default passkey profile, the new schema will take effect. If you continue using Graph API or third-party tools to modify the policy, the schema will not change until General Availability.

These new settings will be available at Entra admin center > Home > Security > Authentication methods > Passkey (FIDO2) settings:

"packed" (self) should be deployed from early January 2026 to early February 2026

MC1164381 (Updated) OneDrive: Simplified file transfer for departing employees Managing OneDrive content for departing employees is now more efficient. Key improvements include:

Redesigned notifications: Account cleanup emails are now more prominent, reducing the chance of being overlooked.

Improved filtering: New filters help managers quickly locate shared or important files.

Bulk file transfer with preserved sharing: The "Move and keep sharing" feature allows multiple files to be transferred while retaining existing sharing permissions.

Consolidated alerts: When six or more files are moved, collaborators receive a single streamlined notification.

These updates help ensure a smooth handover and reduce the risk of losing critical files.

When a user account is deleted, OneDrive access is automatically granted to the manager or designated secondary owner. The recipient receives an email notification with access details and information about the OneDrive retention period. Seven days before the retention period ends, a second reminder email is sent, stating that the OneDrive will be permanently deleted in seven days.

Steps to transfer files:

From the email, click View files to access the departing user's OneDrive.

Use the Shared filter to view only shared files, or All to see everything.

Select files using the checkbox in the table header.

Click Move to, choose a destination, and check Keep sharing with the same people.

Click Move to again to complete the transfer.

Collaborators will receive a single notification once the move is complete:

What you can do to prepare

No admin action is required before rollout. You may want to:

Inform managers and secondary owners about the new experience.

Update internal documentation to reflect the new transfer process.

MC1176303 (Updated) We’re updating how we bill for mid-term subscription changes If you have an account where your invoices start with a "G", your organization will be impacted by this change on the date the change is launched in your region.

Example:

If your account is in Singapore or Italy and you add a license to your subscription on November 13, you will receive an invoice for that additional license on November 14th.

Note: With this change is it possible to be billed later for changes made earlier in the month as changes made prior to this update will still be billed around the beginning of the following month.
If you have an account where your invoices start with a "G" and have purchased directly from Microsoft, your organization will be impacted by this change on the date the change is launched in your region. Purchases made through a partner or a volume licensing agreement are not impacted by this change.

Example

If your account is in Singapore or Italy and you add a license to your subscription on November 13, you will receive an invoice for that additional license on November 14th. Any consumption charges for Azure will continue to be billed on the monthly invoice available at the beginning of the following month.

Additional details about this change

During the month your region transitions:

If you make no changes after the transition, previous changes remain on their original invoice schedule.

If you make changes after the transition, any pending charges from before the transition are invoiced immediately. You'll also receive a separate invoice for the new changes.

MC1111778 (Updated) Microsoft Purview | Information Protection: Sensitivity label grouping modernization Updated September 24, 2025: We have updated the timeline. Thank you for your patience.

Coming soon to Microsoft Purview | Information Protection: To help improve label usability and configuration, the sensitivity labeling scheme will be simplified to only consist of labels and label groupings.

This move to a dynamic architecture will make it easier to move a child label into label groups, out of label groups, and between label groups without losing referential integrity, allowing customers to better scale and reorganize their labels across their entire data estate.

Tenants in scope for manual migration to the new label scheme will see a message on the Sensitivity labels page in the Purview portal, where the tenant admin can access a simple manual migration wizard to opt in to the migration, which should complete in less than a few minutes or even seconds, depending on the label configuration.

If you do not see this message, your tenant does not meet the criteria for manual migration (your tenant lacks applicable parent labels). This new label scheme will be rolled out to your tenant in the coming months. (and we will send a separate MC post in advance).

This message is associated with Microsoft 365 Roadmap ID 386900.

Declarative Agents allow users to customize their Copilot experience by integrating plugins, enterprise connectors, and orchestration logic. This update aligns classic Outlook with other Copilot Chat experiences, delivering consistent agent capabilities across platforms.

This update is tracked under Microsoft 365 Roadmap ID 481559.

[When this will happen:]

General Availability (Worldwide): We will begin rolling out late October 2025 and expect to complete by mid-December 2025.
Updated November 3, 2025: We are making additional fixes which will delay this release. Our updated plan is to make this feature available by end January, 2026. Thank you for your patience.

MC1162958 (Updated) Viva Engage - Retirement of themes in user settings [Introduction]

Microsoft is retiring the themes feature in user settings for Viva Engage. This change removes the ability for users to personalize their Viva Engage interface with custom themes. While usage of themes is low across Viva Engage tenants, this decision was made due to accessibility limitations in the current themes implementation, which conflict with future feature improvements. The retirement now helps pave the way for a new admin-led branding capability that is in development. This new feature will allow organizations to centrally configure visual elements such as logos, brand colors, and names. It is not yet available and will be communicated separately when ready.

Screenshot 1: Themes will no longer appear in Viva Engage settings

[When this will happen:]

This change will be rolled out early November 2025 and completes mid-November 2025.

Updated November 6, 2025: We have updated the timeline. Thank you for your patience.
