Updated May 18, 2026: We have updated the timeline for Phase 2. Thank you for your patience.
What it is
Microsoft is rolling out a new feature to streamline how app 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) and the Teams Admin Center (TAC), which led to mismatches. With this update, you’ll be able to unify availability policies for apps and agents across both portals, making app management more consistent and 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 late September 2025 and expect to complete by August 2026 (previously end of June).
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.
- 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 rolling out this feature in January 2026 and complete rollout by end of July 2026 (previously June).
- This message is associated with Microsoft 365 Roadmap ID 485712 & 503105.
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. We will update this post with a timeline and more details later.
How this will affect your organization
Before this rollout, managing Teams apps that also work in Outlook and the Microsoft 365 app was fragmented across two admin centers:
- the Integrated apps and Agent apps pages in the Microsoft 365 admin center, and
- the Manage apps page in the Teams admin center.
- You’ll gain a consolidated view of agent and Microsoft 365 app availability across both Microsoft 365 and Teams admin centers.
- Changes made in either admin center to the agent and app availability will automatically apply across all supported hosts.
- Organization-wide defaults for both admin centers will be in sync and govern 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 management policies.
