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.

  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.
