Microsoft Teams: App Deployment in Teams Admin Center

🚨 The Signal: Teams app deployment now offers granular control over pre-installation for specific users/groups, replacing broad app setup policies. This enhances security by allowing precise app distribution.

The Impact

Admins are affected by new app deployment controls, reducing the risk of unauthorized or unnecessary app installations.

• Admins: New controls require review of existing app setup policies.
• Security Teams: Reduced attack surface from more precise app deployment.
• Users: Less clutter from unwanted pre-installed applications.
• Compliance Teams: Improved ability to meet application control requirements.

The Action

1. Review existing Teams app setup policies in Teams Admin Center.
2. Identify apps currently deployed via 'Installed apps' section.
3. Transition app deployment to the new per-app controls for specific users/groups.
4. Implement a phased rollout for critical applications to validate deployment.
