Microsoft Roadmap, messagecenter and blogs updates from 24-09-2025

Updated September 23, 2025: We have updated the timeline. Thank you for your patience.

With this rollout, if no room is booked for the meeting, an AI-generated room suggestion will be sent in the meeting chat an hour before the meeting start time when two or more attendees are co-located in the same building, making in-person collaboration easier. The room suggestion will consider location of participants, room availability, and capacity to find the best space. You can reserve the suggested room with just one click and update the invite for everyone. The organizer must have a Teams premium license for this experience to occur, which is on Teams mobile on iOS.  #MicrosoftPlaces

[When this will happen:]

General Availability (Worldwide): We will begin rolling out mid-November 2025 and expect to complete by late November 2025

[How this will affect your organization:]

This will be a default on feature.

For a room suggestion to be generated, a meeting must have:

• Between two to seven attendees with at least two attendees that are co-located
• Teams meeting link
• Organizer has Teams premium
• No room is already booked for the meeting
• No external attendees
• Not an all-day event 

Room suggestions will be generated in buildings where at least two attendees, who haven’t declined the meeting, share the same work location. For instance, if a meeting has four attendees, with two in Building X and two in Building Y, suggestions for both buildings will be sent. Distribution lists are not considered.

If a meeting is moved, canceled, or the suggested room becomes unavailable, the card will update dynamically upon clicking ‘Reserve’.

[What you need to do to prepare:]

This rollout will happen automatically by the specified date with no admin action required before the rollout. You may also want to notify your team about this change and update any relevant documentation. We recommend making sure that your rooms are properly added to Places directory with a building associated.

The new Microsoft Planner for the web (https://planner.cloud.microsoft) brings together the simplicity of Microsoft To Do, the collaboration of Planner, and the advanced capabilities of Microsoft Project into one platform. Planner for the web offers a comprehensive and scalable solution, whether users are managing individual tasks or overseeing professional-grade projects. All users with an existing Project for the web license will have access to Planner. (A Microsoft Teams license is also required to use Planner in Teams.)

Starting early August 2025, we will retire Project for the web and will redirect its users to Planner for the web and Planner for Teams, for a smooth transition.

Premium plans from Project for the web automatically will be available in Planner, ensuring users experience a seamless migration without losing any data.

We will add these capabilities to Planner before the redirect goes into effect:

• Users will be able view and manage non-default environment plans in Planner.
• We will rename Project Power app to Planner power app (and the button to open the plan in Project will be replaced with a button to open the plan in Planner).
• Project settings in the Microsoft 365 admin center will move to the Planner page in the admin center.
• Tenants with only Project licenses will be able to access basic plan functionality in Planner.
• We will roll out the new Planner to GCC High.

User experience in Project and Roadmap for the web and Teams

• When launching Project for the web or Roadmap for the web, users will see a page directing them to open Planner for the web, they will not be able to dismiss this screen or use Project or Roadmap for the web.
• Existing Project tabs in Teams will no longer open the associated project, and instead will show users a page to inform them to re-pin their tab using the Planner tab for Teams
• Existing Roadmap tabs in Teams will no longer open the associated roadmap, and instead will show a page directing users to the Planner app in Teams
• Users will no longer have access to view or create Roadmaps in Project for the web, but their Roadmap data will remain in Dataverse
• We will remove the Project tab and Roadmap tab apps from the Teams app store.

[When this will happen:]

• For Worldwide: We will begin rolling out early August 2025 and expect to complete by mid-August 2025.
• For GCC: We will begin rolling out mid-August 2025 and expect to complete by late August 2025.
• For GCC High: We will begin rolling out late August 2025 and expect to complete by late September 2025 (previously mid-September).

[How this will affect your organization:]

Due to low usage and our efforts to simplify the user experience, these Project for the web features are not available in Planner:

• Users will need to migrate their existing Roadmaps to Portfolios because Planner does not support opening roadmaps. Learn more about migrating Roadmaps to Portfolios: Manage multiple plans with portfolios in Microsoft Planner – Microsoft Support
• Portfolios in Planner do not support adding rows for Microsoft Azure DevOps or Microsoft Project Online
• Import MPP is not available in Planner. Learn more about how to use the Project Power App to import projects from Microsoft Project for Windows desktop: Move your project from Project desktop to Project Power Apps – Microsoft Support
• Users are not able to pin Portfolios as a Teams tab
• Activity reports in Admin Center are not available for premium plans in Planner.
• The ability to add new Roadmap items from within Project Online will be removed.

[What you need to do to prepare:]

• This retirement will happen automatically by the specified dates with no admin action required before or after the rollout. Review your current configuration to assess the impact on your organization.
• You may want to notify your users and update any internal documentation to reflect these changes.
• Migrate existing Roadmap data to Portfolios in Planner before the redirect rollout date.
• Inform your users to proactively re-pin your Projects in Teams tabs using the Planner in Teams tabs
• Start using Planner in your organization today to minimize disruption when the redirect is rolled out
• Supporting adoption resources: The new Microsoft Planner

[When this will happen:]

General Availability (Worldwide): We will begin rolling out mid-July 2025 and expect to complete by late October 2025 (previously mid-September).

[How this will affect your organization:]

When users receive an email from an unverified sender, they will see a banner in the reading pane explaining why the sender is flagged and warning about potential impersonation. This complements existing safety messages such as:

• “External sender”
• “Not on safe senders list”
• “You don’t often get email from this sender”

This feature is available by default when the unverified signal is received by the service. There are no admin controls to configure or disable this functionality.

[What you need to do to prepare:]

No admin action is required. However, we recommend informing your users about this new visual cue and its purpose. If your organization provides internal training or documentation on email safety, consider updating it to include this new banner.

Introduction

We’re introducing support for Microsoft Purview sensitivity labels in OneNote. This update enables users to classify and protect OneNote sections using the same compliance standards available across Microsoft 365 apps. Labels can be applied directly within OneNote, helping ensure sensitive content is encrypted, access-controlled, and aligned with organizational policies. This change supports consistent data protection across platforms and endpoints.

This message is associated with Microsoft 365 Roadmap ID 500020.

When this will happen

General Availability (Worldwide, GCC, GCCH, and DoD): We will begin rolling out on late January 2026 and expect to complete by late January 2027.

How this affects your organization

This update enhances data protection and compliance capabilities by extending sensitivity labeling to OneNote sections. Admins will gain greater control over how sensitive information is handled within OneNote, aligning it with other Microsoft 365 apps. This is particularly beneficial for organizations in regulated industries, helping mitigate risk and enforce compliance policies across endpoints.

Who is affected:

All users of supported OneNote clients across platforms, including organizations in regulated industries and those with compliance requirements.

What will happen:

• Sensitivity labels will be available in supported OneNote clients:
  • OneNote Win32 (Desktop)
  • OneNote for Web
  • OneNote for iOS
  • OneNote for Android
  • OneNote for Mac
• OneNote for Windows 10 (UWP) will not support this feature.
• Users will be able to apply sensitivity labels directly to OneNote sections.
• Labeled sections will be encrypted and access-controlled based on organizational policies.
• Admins can enforce labeling policies and monitor usage via Microsoft Purview.
• Label policies can be scoped using Entra ID group membership.

What you can do to prepare

To prepare for this rollout:

• Ensure endpoints are using supported OneNote clients: Win32, Web, iOS, Android, and Mac.
• Transition away from OneNote for Windows 10 (UWP), which will not support sensitivity labels.
• No additional setup is required beyond maintaining updated builds.
• Admins may want to validate readiness and communicate expected changes to users.
• Review and update internal documentation to reflect supported platforms.

Coming soon to Microsoft Purview: Insider Risk Management (IRM) data including alerts, indicators and events will be available in these Microsoft Defender XDR experiences:

• Unified alert queue: IRM alerts will appear in the unified alert and incident queue in Defender XDR for comprehensive investigation and correlation.
• Advanced Hunting: IRM data will be available for advanced hunting in Defender XDR, allowing analysts to identify hidden risk patterns using KQL queries. Analytics can also create custom detections on the top of IRM data.
• Graph API: IRM data will be accessible through the Microsoft Graph API, supporting bidirectional integrations with external applications.
• Microsoft Sentinel: IRM alerts will be available in Microsoft Sentinel through the XDR-Sentinel connector, providing richer metadata.

This message is associated with Microsoft 365 Roadmap ID 422730.

[When this will happen:]

Public Preview: We will begin rolling out mid-January 2025 and expect to complete by end of January 2025.

General Availability (WW, GCC, GCC High, DoD): We will begin rolling out late August 2025 (previously late June) and expect to complete by mid-October 2025 (previously mid-September).

[How this will affect your organization:]

Enable this feature by turning on Share data with other security solutions in the IRM global settings.

Only users with Insider risk analysis or investigation roles in the Microsoft Purview portal can access IRM data in Defender XDR.

To access alerts, incidents, and events from Defender XDR via API, you need to provision apps with the necessary permissions. IRM data is accessible via Microsoft Security Graph APIs, allowing for reading and updating alert or incident statuses. Permissions are set at the application level, without solution-specific scoping. Any existing apps pulling data from these APIs will also access IRM data. So, if you integrate XDR alerts into external ticketing systems, IRM alerts will show up, unless you specifically filter out the alerts.

IRM alerts will appear in Sentinel if your tenant has the Defender XDR connector enabled in Microsoft Sentinel.

In Defender XDR, IRM data is not pseudonymized to allow effective correlation of IRM alerts with alerts from other solutions within the platform, such as Defender for Endpoint and Defender for Cloud apps.

These changes will be available by default for admins to configure in IRM global settings.

Admins will be able to view Insider Risk Management alerts in Defender XDR:

Harness the power of Advanced Hunting queries with two new tables that contain Insider Risk Management data: DataSecurityBehaviors and DataSecurityEvents. In this query, 54 confidential files were exfiltrated through mail.google.com by 2 unique users:

[What you need to do to prepare:]

• Opt-in to data sharing settings in IRM global settings page.
• Assign necessary permissions to analysts
• Review existing apps accessing Defender XDR data through Graph APIs.
• If your organization is using Microsoft Defender XDR connector, please review the list of users who will gain access to this data through Sentinel.

This rollout will happen automatically by the specified date with no admin action required before the rollout. Review your current configuration in IRM global settings to determine the impact for your organization. You may want to notify your admins about this change and update any relevant documentation.

Updated September 23, 2025: We have updated the timeline. Thank you for your patience.
