MC796790 - Microsoft 365 and Microsoft Teams: Unified management of Teams apps in Teams, Outlook, and the Microsoft 365 app

Updated August 13, 2026: We have updated the content. Thank you for your patience.March 26, 2025: This change is now on hold, with further guidance to be provided by late April 2025. 

What it is

In 2023, we introduced Microsoft is rolling out a new feature to streamline how appTeams apps that are compatible with Microsoft Outlook 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)App (manifest version v1.13 or higher). Before this rollout, admin changes made in the Integrated apps section of the Microsoft 365 admin center would only affect these Teams apps in Outlook and the Microsoft 365 app. Similarly, changes made in the Teams Admin Center (TAC), which ledadmin center would exclusively affect Teams. Starting in June 2024, we will roll out Unified App Management to mismatches. With this update, you’ll be able to unify availabilitystreamline the management of these apps across Teams, Outlook and installation policies for apps and agentsthe Microsoft 365 App, so they are consistently available across both portals, making app management more consistent and efficient.all supported clients.

When this will happen:

This rollout will happen in two major phases. Unified App Management can apply only to tenants that have migrated to app centric management in Teams admin center, as communicated in MC688930 (Updated) Teams admin center: App centric management and changes to app permission policies (November 2023).

• Phase 1 | General Availability (Worldwide): We will begin rolling out this featurelate-January 2025 (previously mid-December 2024) is now on hold (previously late September 2025 and expectMarch 2025), with further guidance to completebe provided by August 2026 (previously end of June).

  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 Septemberlate April 2025. This initial phase targetsapplies to tenants that have neverwith no modified their organization-wide defaults, app availability, or block/unblocksettings in either the Microsoft 365 admin center (Integrated apps) or the Teams admin center. At the end ofcenter for organization-wide defaults, app deployment, app availability, or block/unblock. No merge rules apply to these tenants, but after this phase, agentany app management setting configured in either admin centers will apply to all relevant hosts.

• Phase 2: We will update this post with a timeline and more details in April 2025 (previously March 2025).  This phase is applicable to tenants with app manageability will be unified across bothsettings that have differences between Microsoft 365 admin center (Integrated apps) and Teams admin center ensuring agent and Microsoft 365 apps availability policies are in alignment for all future administrative changes.

  center.

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.

1. 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.

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.

1. 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. This has been rolled out completely for all tenants.
2. 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 transitioned as part of Phase 1 & Phase 2, will be automatically moved to unified app agent management. We’ll update this post later with the timeline and additional details, with advance notice.

B: Unify app installation across admin centers

Timeline: We will begin rolling out this phase late August 2026 and expect to complete by mid-September 2026

In this phase, app and agent installation management is unified across the Teams admin center and Microsoft 365 admin center. Admins can manage supported app and agent installations from either portal, and changes remain synchronized across both experiences. For tenants already moved to a unified state in Phase 1 or Phase 2, no additional action is required. Their existing eligible installation assignments will remain synchronized across both admin centers.

Important: App installation is no longer managed through Teams app setup policies. App installations previously made through app setup policies are not unified as part of this change.

How this will affect your organizationorganization:

Before this rollout, managing Teams apps that also work in Outlook and the Microsoft 365 app was fragmented across two admin centers:

1. between the Integrated apps and Agent apps pagesapps page in the Microsoft 365 admin center,center for Outlook and
2. the Manage apps page inMicrosoft 365 app, and the Teams admin center.

app in the two admin centers. With Unified agentApp Management, we will be consolidating app management, admins cancatalog management into a single platform. You will be able to manage apps and agents from eitheron the Integrated apps page in the Microsoft 365 admin center or in the Teams admin center. Availability settings will remain synchronized across both, ensuring a consistent management experience.

What you can expect:

1. You’ll gain a consolidated view of agentcenter, and Microsoft 365 app availability across both Microsoft 365 and Teams admin centers.
2. Changesany changes made in either admin center will synchronize.

   2. Organization-wide settings: App availability default settings will now apply to apps used in Teams, Outlook, and Microsoft 365 app.
   3. App installs: Apps deployed from the Integrated apps page in Microsoft 365 admin center will be preinstalled in all applicable hosts for the app. Unlike app preinstallation in the Teams App setup policy, new app installs will provide access to the agent andpreinstalled apps, similar to deploying the app availability will automatically apply across all supported hosts.
   4. Organization-wide defaults for both admin centers will be in sync and govern app availability across Teams, Outlook,Outlook and the Microsoft 365 copilot app.App. For more details on app deployment, refer to MC795355 Microsoft Teams admin center: App centric management for app installation and changes to app setup policies (May 2024).

   8. Consolidation report: After further review we have decided not to proceed with this change at this time. We apologize for any inconvenience.
