Admin app retiring in Teams, Outlook and Microsoft365.com

🚨 The Signal: The 'Admin app' in Teams, Outlook, and Microsoft365.com, designed for very small businesses, will be retired by October 2026. This removes a simplified admin interface, requiring use of the full Microsoft Admin Center.

The Impact

Very small business admins are affected, with minimal security risk as the full admin centers offer equivalent or better security controls.

• Small business admins: Must adapt to using the full Microsoft Admin Center.
• Security teams: No direct security risk, but ensure admin roles are correctly assigned in the main admin centers.

The Action

1. Review existing administrative roles and permissions in Microsoft Admin Center (admin.microsoft.com).
2. Familiarize very small business administrators with the Microsoft Admin Center interface.
3. Evaluate the utility of the Microsoft 365 Admin Agent for delegated administrative tasks.
