What it is now on hold, with further guidance

Microsoft is rolling out a new feature to be provided by late May 2025. 

In 2023, we introducedstreamline how app and agent availability is managed across Teams, Outlook, and Microsoft Teams apps that are compatible with Microsoft Outlook and365 Copilot. Until now, IT admins configured availability settings separately in both the Microsoft 365 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 OutlookAdmin Center (MAC) and the Microsoft 365 app. Similarly, changes made in the Teams admin center would exclusively affect Teams. Starting in June 2024, we will roll out Unified App ManagementAdmin Center (TAC), which led to streamline themismatches. With this update, you’ll be able to unify availability policies for apps and agents across both portals, making app management of these apps across Teams, Outlookmore consistent and the Microsoft 365 App, so they are consistently available across all supported clients.efficient.

  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. No merge rules apply to these tenants, but after this phase, any app management setting configuredunblock settings in either admin centerscenter.
