MC796790 - Unified management of app and agent availability and installation in Teams, Outlook, and the Microsoft 365 app

Updated November 18, 2025:October 1, 2026: We have updated the timelinecontent and content below.timeline. Thank you for your patience. 

What it is

Microsoft is rolling out a new feature to streamline how app and agent availability and installation is managed across Teams, Outlook, and Microsoft 365 Copilot. Until now, IT admins configured availability and installation settings separately in both the Microsoft 365 Admin Center (MAC) and the Teams Admin Center (TAC), which led to mismatches. With this update, you’ll be able to unify availability and installation policies for apps and agents across both portals, making app management more consistent and efficient.efficient.

This message is associated with Microsoft 365 Roadmap ID 393931, 485712 and 503105.

When this will happen: 

We will begin rolling out this feature

• App and agent AVAILABILITY unification (section A): Rollout began in late September 2025. The Phase 3 timeline will be announced separately, at least 60 days before that phase begins.
• App and expect to complete by agent INSTALLATION unification (section B): Rollout begins at the end of JuneSeptember 2026 (previously mid-November 2025). 

A: Unify app availability across admin centers

1. Phase 1 – Default Tenant Unification of App/Agent Availability

We will begin rolling out this feature at the end of September 2025. This initial phase targets tenants that have never modified their organization-wide defaults, app availability, or block/unblock in either the Microsoft 365 admin center or the Teams admin center. At the end of this phase, agent and app manageability will be unified across both Microsoft 365 admin center and Teams admin center ensuring agent and Microsoft 365 apps availability policies are in alignment for all future administrative changes. This message is associated with Microsoft 365 Roadmap ID 393931.

2.Phase 2 – Modified Tenants Unification of App/Agent Availability

This phase targets tenants that have previously modified their organization-wide defaults, app availability, or block/unblock settings in either admin center. These tenants will be transitioned to a unified management experience across both Microsoft 365 and Teams admin centers.

• For tenants with no agent or app availability differences across both admin centers, guidance will be provided to help maintain unified availability policy for all future changes. We will begin rolling out this feature in early November 2025.
  
  • This message is associated with Microsoft 365 Roadmap ID 503105.

• For tenants with agent or app availability differences across both admin centers, a wizard in the Teams admin center will help identify affected agents and apps and guide through resolving discrepancies.

  • As part of this phase we will also enable administrators to manage Microsoft 365 certified SaaS applications within their tenant through org-wide settings for third-party apps. We will begin rollingThis has been rolled out this feature in January 2026.
    completely for all tenants.
  • This message is associated with Microsoft 365 Roadmap ID 485712 & 503105.

This phase has been fully rolled out to all tenants. Tenants can choose to align through the wizard experience available in Teams admin center.

Note: In this phase, no changes will be applied to org-wide settings or app-level settings without administrator action.

3. Phase 3 – Automatic Unification (Future)

Tenants that haven’t transitionedhave not taken action to unify availability through the wizard experience released in Phase 1 and Phase 2 will have their availability automatically unified across MAC and TAC as part of Phase 1 & Phase 2, will be automatically moved to unified app agent management.this phase. We will update this post with ainform customers of the timeline and moreadditional details later.at least 60 days in advance before this phase begins.

How this will affect your organizationB: Unified app and agent installation management 

Before this rollout, managing Teams apps that work in Outlook and the Microsoft 365 app was fragmented between the Integrated apps page in the Microsoft 365 admin center for Outlook and the Microsoft 365 app, andThis capability unifies installation management across the Teams admin center for Teams. This sometimes resulted in different settings for the same app in the two admin centers. With Unified agent app management, you will be able to manage apps on the Integrated apps page in theand Microsoft 365 admin center or in the Teams admin center,center. Administrators can manage supported app and anyagent installations from either portal, with changes made in either admin center will synchronize.

• You’ll gain a consolidated view of agent and Microsoft 365 app availabilitysynchronized across both Microsoft 365 and Teams admin centers. 
• Changes made

  Who receives this capability? 

  Tenants whose app and agent availability has been unified through any of the phases described in either admin centersection A are eligible. Once rollout begins, this capability will be automatically enabled for tenants whose availability is already unified as part of Section A. Tenants that unify their availability later will receive this capability automatically once unified. 

  Note: This capability is separate from availability unification described in section A . It does not automatically unify app or agent availability. 

  When will it roll out? 

  Rollout will begin at the end of September 2026 for eligible tenants. This date applies only to the agentinstallation management (section B). 

  Is administrator action required? 

  No additional action is required to enable installation unification for eligible tenants. Existing installation assignments for supported apps and app availabilityagents will automatically applybe synchronized across all supported hosts.

• Organization-wide defaults for both admin centers will be in sync and governcenters. 

  Important: App installation is no longer managed through Teams app availability across Teams, Outlook, and the Microsoft 365 copilot app.

 What you need to do to prepare

To ensure a smooth transition, review your tenant-level and individual agent/app settings (app allow/block & user availability) in both the Microsoft 365 Admin Center and the Teams Admin Center. If different departments within your organization manage these settings, we suggest coordinating efforts to complete the review collaboratively.

This update will be rolled out automatically by the stated date, and no immediate action is required. However, it's a good time to update any internal documentation related to agent and app managementsetup policies. Installations previously made through those policies are not unified as part of this change.
