Org-wide app settings control overarching app behaviors, such as whether third-party apps are allowed, but do not allow for granular control over which specific apps are available from a defined list.

Manually blocking every unapproved app from the Manage apps page would be a high administrative effort, as new apps are constantly added, making it an impractical solution for maintaining a restricted allow list.

App permission policies in the Microsoft Teams admin center control which apps are available to users within their Teams app store. By configuring the global (Org-wide default) app permission policy, an administrator can block all apps by default and then explicitly allow only the specified apps, thereby minimizing the administrative effort to create a restricted allow list.

App setup policies determine which apps are pre-installed or pinned for users, but they do not control which apps are available for users to discover and install from the Teams app store.
