The Admin app was designed to simplify Microsoft 365 administration for very small businesses by bringing a focused set of common admin capabilities into Teams, Outlook, and Microsoft365.com.
Microsoft is now retiring that experience, with the change rolling out in two stages.
- Phase 1 — August 2026: The Admin app will no longer be pre-pinned or pre-installed in Teams for new very small business admins. Existing users may continue to access it if the app is already installed.
- Phase 2: October 2026: The Admin app will be retired completely and will no longer be supported or available in Teams, Outlook, or Microsoft365.com.
For organizations that have incorporated the app into their day-to-day administration workflow, it’s time to move those tasks to Microsoft’s dedicated management experiences.
Alternative for Admin App for Small Businesses
We should fall back to:
- Microsoft 365 Admin Center: tenant administration, users, licenses, billing, service health, and broader Microsoft 365 management.
- Teams Admin Center: Teams policies and configuration, users, apps, meetings, messaging, voice, and Teams service management.
- Microsoft 365 Admin Agent: an AI-assisted administration experience that can help admins perform and streamline certain management tasks.
To be clear: this is a retirement of the Admin app, not of Microsoft 365 or Teams administration. Microsoft is effectively moving admins away from the simplified, consolidated app experience and back toward the dedicated admin centers and newer AI-assisted administration capabilities.
If your tenant still runs on the Admin app, this is the window to migrate before October.
Do you currently use the Admin app for Microsoft 365 administration? Was its consolidated experience useful, or do you prefer working directly from the dedicated admin centers?
