Use app permission policies to control user access to apps
As an admin, you can use app permission policies to control the apps that are available to each user in your organization. The permissions you set to allow or block all apps or specific apps are applicable to all types of apps in Teams. You must be a Global Admin or Teams service admin to manage these policies.
To allow an app, you must allow it in Org-wide app settings, individual app's setting, and app permission policy. While the other two methods just allow an app for use in your organization, the permission policies allow you to control which users can use a specific app. You control access on a per-user and per-app basis by creating and applying the policy to specific users.
Teams admin center lets you create two types of permissions policies:
Global (Org-wide default)policy exists by default and applies to all users. Any changes made to this policy impact all users as this policy is applied to all users by default.
An admin-created policy applies only to the users that it is applied to. Create a new policy to allow apps for specific users or group of users.
If your organization is already on Teams, the app settings you configured in Tenant-wide settings in the Microsoft 365 admin center are reflected in org-wide app settings on the Manage apps page in Teams admin center. If you're new to Teams and just getting started, by default, all apps are allowed in the org-wide global setting. It includes apps published by Microsoft, third-party software providers, and your organization.
To know about third-party app settings in Microsoft 365 Government Community Cloud High (GCCH) and Department of Defense (DoD) environment, see Manage org-wide app settings for Microsoft 365 Government.
Create an app permission policy
Use one or more custom app permission policies, if you want to control the apps that are available for different groups of users. You can create and assign separate custom policies based on whether apps are published by Microsoft, third-parties, or your organization. After you create a custom policy, you can't change it if third-party apps are disabled in org-wide app settings.
Sign in to Teams admin center and access Teams apps > Permission policies.
Provide a name and description for the policy.
Under Microsoft apps, Third-party apps, and Custom apps, select one of the following options:
- Allow all apps
- Allow specific apps and block all others
- Block specific apps and allow all others
- Block all apps
If you selected Allow specific apps and block all others, add the apps that you want to allow:
- Select Allow apps.
- Search for the apps that you want to allow, and then select Add. The search results are filtered to the app developer (Microsoft apps, Third-party apps, or Custom apps).
- After choosing one or more apps, select Allow.
If you selected Block specific apps and allow all others, similarly search for and choose the apps that you want to block, and then select Block.
Edit an app permission policy
You can use the Teams admin center to edit the global policy or any custom policies that you've created.
- Sign in to the Teams admin center and access Teams apps > Permission policies.
- Select the policy by clicking to the left of the policy name, and then select Edit.
- Make the changes to allow or block specific apps in each of the three categories.
- Select Save.
Assign a custom policy for app permissions to users
App permission policies take effect only when you apply a policy to a user or a group of users. See the different ways to assign the policy to users.
Considerations when using app permission policies
The following are a few considerations when using app permissions policies to grant access or to disallow access to apps:
App permission policies take effect only when you apply a policy to a user or a group of users.
After you edit or assign a policy, it can take a few hours for changes to take effect.
An end-user cannot interact with any functionality of an app that the user is not allowed to use.
Users can search for blocked apps and request admin approval. Admins retain complete control to approve or ignore user requests.
App setup policies work together with app permission policies. You select apps to pin in setup policy from a set of allowed apps. However, if a user has an app permission policy that blocks the use of a pinned app, then the user cannot use the app.
App policies apply to users using any Teams on web, mobile, or desktop.
