What should you modify to prevent third-party apps from being used from Microsoft Teams at the company?

 

To prevent third-party apps from being used in Microsoft Teams at the company level, you can configure the Global (Org-wide default) App permission policy.  App permission policies in Microsoft Teams allow administrators to control which third-party apps are allowed or blocked for users within the organization.  By adjusting the app permission settings in the permission policy, you can control whether users in your organization can use third-party apps in Microsoft Teams.

The process of modifying the Global (Org-wide default) App permission policy involves several key steps:

• Accessing the Microsoft Teams Admin Center: Begin by logging into the Microsoft Teams Admin Center using administrative credentials. This centralized dashboard provides access to a range of administrative settings, including app permission policies.
• Navigating to App Permission Policies: Within the Teams Admin Center, navigate to the "Teams apps" section and select "Permission policies." Here, you'll find a list of existing app permission policies, including the Global (Org-wide default) policy.
• Modifying App Permission Settings: Select the Global (Org-wide default) policy to access its settings. Within the policy configuration, you'll find options to allow or block specific types of apps, including third-party apps. Adjust these settings according to your organization's requirements to prevent the usage of third-party apps.
• Fine-Tuning App Permissions: In addition to blocking third-party apps, you can fine-tune app permissions based on categories such as apps developed by Microsoft, custom apps, and external apps. For example, you may choose to allow certain trusted third-party apps while blocking others based on their security and compliance ratings.
• Reviewing and Applying Changes: Before finalizing the modifications, review the changes made to the Global (Org-wide default) App permission policy to ensure they align with your organization's app usage policies and security requirements. Once satisfied, apply the updated policy to enforce the desired restrictions on third-party app usage within Microsoft Teams.
• Communicating Policy Changes: Communicate any changes to app usage policies, including restrictions on third-party apps, to users and stakeholders within the organization. Provide guidance on approved apps and alternative solutions for specific business needs to ensure a smooth transition and user understanding.

By leveraging the Global (Org-wide default) App permission policy in Microsoft Teams, administrators can proactively manage app usage and mitigate potential security risks associated with unauthorized third-party apps. This level of control helps organizations maintain a secure and compliant collaboration environment while supporting productivity and innovation through approved app integrations.
