If you want to configure that only specific users have access to the Microsoft Teams or Outlook Email integration, please follow these instructions.
As an admin, please visit the Microsoft Teams admin center.
You can use app permission policies to control what apps are available to Microsoft Teams users in your organization. You can allow or block all apps or specific apps published by Microsoft, third parties, and your organization. If you block an app, users who have the policy are unable to install it from the Teams app store. You must be a global admin or Microsoft Teams service admin to manage these policies.
