Microsoft Roadmap, messagecenter and blogs updates from 08-04-2026

Updated April 7, 2026: We have updated the timeline. This feature will now be included as part of another update referenced in MC796790. Administrators will gain the ability to manage Microsoft 365 certified SaaS applications through org-wide settings for third-party apps. No changes will be applied to tenant-wide settings unless initiated by an administrator. Thank you for your patience.

This feature will empower administrators to manage the availability of trusted Microsoft Teams apps based on rules, for enhanced security. Admins will be able to manage Microsoft 365 certified apps in the Teams admin center through a new control in Org-wide settings. You can further customize the availability of these apps based on permissions accessed and publisher names. The system automatically checks the Microsoft 365 certified apps that meet all the conditions you specify and makes those apps available.

You can configure additional criteria from the Customize availability option:

[Introduction]

We’re introducing a new flexible layout option in future Teams meetings to give users more control over how shared content and participant videos appear. A resizable divider will let users adjust the space between shared content and the video gallery. Want to focus more on the presentation? Expand the content area. Prefer to see more people? Shrink the content area to make room for more video tiles. Users can also swap the position of content and participants to suit their viewing preference. This works with spotlighted speakers, pinned videos, and Speaker View, providing a more personalized meeting experience—especially helpful on larger or ultra-wide screens.

Screenshot 1: When someone is sharing content or when you are in Speaker view, grab the divider between the left and right views to resize them.

Screenshot 2. When you drag the divider to the left, you will see more people in the right gallery view. When you drag the divider to the right, you will see less people in the gallery but the content or speaker will become larger.

[Introduction]

Microsoft 365 Copilot Tuning is introducing new templates in Agent Builder designed for tasks such as drafting complex documents, validating documents against organizational guidelines, and editing to match a distinct writing style. Users with Copilot Tuning enabled can further customize the template-based agents by tuning the context, tools, and underlying models with their organization’s proprietary data, processes, and standards. This empowers your teams with customized agents aligned to how your organization works.

[When this will happen]

Public preview (Worldwide): Starting April 2026, Copilot Tuning will be available to organizations with 5,000 or more Microsoft 365 Copilot licenses enrolled in Frontier TAP and Public program and in Preview.

[How this affects your organization]

Who is affected:

Copilot Tuning will be available to organizations with 5,000 or more Microsoft 365 Copilot licenses enrolled in the Frontier TAP and Public program and in Preview.

What will happen:

• New agent templates will become available in Agent Builder for all users licensed for Microsoft 365 Copilot.
• Users can immediately use these templates to build agents for common Microsoft 365 tasks.
• Organizations with 5,000+ Copilot licenses can tune agents by adjusting:
  • Context
  • Tools
  • Models

Data handling, privacy, and residency

• Copilot Tuning creates a snapshot of user‑selected SharePoint content solely for tuning the agent.
• Snapshots are stored in a tenant‑isolated Microsoft 365 environment and are used only within the Copilot Tuning service.
• DLP policies applied to the source SharePoint content do not apply to the snapshot.
• During public preview:
  • Snapshot data is retained while the tuned agent remains active.
  • Snapshot data is deleted when the tuned agent is deleted.
  • Data used for tuning may be retained for up to two years unless deleted earlier.
• Copilot Tuning does not change Microsoft 365 data commitments; all data remains within the Microsoft 365 service boundary under existing Microsoft 365 Copilot privacy and security commitments.
• Snapshot metadata may be requested through Microsoft Customer Support.
• Snapshots are not automatically updated; if underlying SharePoint content changes, agents must be retrained.

Regional processing

• During public preview:
  • EU tenant traffic remains within the EU Data Boundary.
  • Global tenant traffic may be processed in other regions for large language model operations.
  • Microsoft personnel do not access customer data unless explicitly requested by the customer and approved through Customer Lockbox.

Advanced Data Residency (ADR)

• Copilot Tuning is not enabled by default for tenants with ADR during public preview.
• ADR customers may opt in by formally waiving ADR requirements through their Microsoft account team.
• If waived, snapshot data is stored in the nearest macro region in a tenant‑isolated Microsoft 365 environment and governed by existing Microsoft 365 Copilot data protection commitments.

[What you can do to prepare:]

Admins can:

• Manage and restrict access to Copilot Tuning in the Microsoft Admin Center by navigating to: Copilot > Settings > Copilot Tuning
• Scope tuning access to specific users or groups or disable it entirely.
• Review internal data governance, privacy, and regulatory requirements before enabling tuning.
• Communicate the new capability to internal support teams if needed.
• Update internal documentation as appropriate.

Updated September 9, 2025: We have updated the timeline. Thank you for your patience.

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.

[When this will happen:]

Targeted release: We will begin rolling out mid-January 2025 (previously early January) and expect to complete by mid-January 2025 (previously mid-December).

General Availability (Worldwide, GCC): We will begin rolling out early March 2026 and expect to complete by late March 2026.  

[How this will affect your organization:]

When co-organizer opens the event scheduling page, they should have the ability to edit the details page, publish, and cancel the event. 

[What you need to do to prepare:]

Nothing required to prepare.
