Updated MayDecember 18, 2026:2024: We have updated the rollout timeline for Phase 2.below. Thank you for your patience.
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 is managed across Teams, Outlook, and Microsoft 365 Copilot. Until now, IT admins configured availability 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 availability policies forstreamline the management of these apps across Teams, Outlook and agentsthe Microsoft 365 App, so they are consistently available across both portals, making app management more consistent and efficient.all supported clients.
This message is associated with Microsoft 365 Roadmap ID 393931, 485712 and 503105.
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).
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 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 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 deployment, app availability, or block/unblock settingsunblock. No merge rules apply to these tenants, but after this phase, any app management setting configured in either admin center. These tenantscenters will be transitionedapply to a unified management experience across both Microsoft 365 and Teams admin centers.
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
Tenants that haven’t transitioned as part of Phase 1 & Phase 2, will be automatically moved to unified app agent management.2: We will update this post with a timeline and more details later.in March 2025. This phase is applicable to tenants with app settings that have differences between Microsoft 365 admin center (Integrated apps) and Teams admin center, and who have maintained a single app setup policy in Teams that has a modified Installed apps section.
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:
