Microsoft Teams is set to introduce a significant update that will empower administrators with enhanced control over third-party app availability through new rule-based settings in the Teams admin center. This feature, detailed in Microsoft's Message Center update MC1085133, is scheduled to begin its global rollout in mid-August 2025, with completion expected by early September 2025. The update, identified under Microsoft 365 Roadmap ID 485712, allows admins to manage Microsoft 365-certified apps in bulk directly from the Teams admin center.
Current Limitations in App Management
Previously, the availability of third-party apps within Microsoft Teams was governed solely by tenant-wide settings, offering limited flexibility and control to administrators. This approach often posed challenges in ensuring that only trusted and compliant applications were accessible to users, potentially exposing organizations to security risks.
Introduction of Rule-Based App Management
With the upcoming update, administrators will gain the ability to set rules based on app permissions and publisher names, ensuring that only trusted, certified apps are accessible to users. This rule-based approach allows for more granular control over app availability, enabling organizations to tailor their app ecosystems to meet specific security and compliance requirements.
Automatic Enablement and Default Settings
A key aspect of this rollout is the automatic enablement of the feature, meaning it will be turned on by default for all organizations. The system will automatically evaluate Microsoft 365-certified apps against the rules specified by the admin, making compliant apps available to users. This move aims to bolster security and streamline app management across organizations.
Implementation Details
Once the feature is live, administrators can access the new controls via the Teams admin center under Manage apps > Actions > Org-wide app settings > Microsoft 365 certified apps. The default setting will allow all certified apps, but admins can further refine availability using the new "Customize availability" option. This enables granular control based on specific criteria, such as required permissions or trusted publishers.
Action Items for Organizations
- Automatic Rollout: No immediate action is required from admins before the feature launches.
- Review and Notify: Admins are encouraged to review their current app configurations and notify users of the upcoming changes. Updating internal documentation is also recommended.
- 30-Day Grace Period: After the feature releases in a tenant, organizations will have 30 days to adjust settings before the new rules impact app availability. This grace period is a one-time occurrence for this launch; subsequent changes will take effect immediately.
This update represents a significant step forward in enhancing the security and manageability of third-party apps within Microsoft Teams, providing administrators with the tools needed to ensure a compliant and secure app environment.
