Disable the Office 365 Store for Users
While the Office 365 Store offers some useful software, some administrators will want to prevent users from installing third-party Office add-ins on their own. These administrators can turn off the Office 365 Store tile in the Office 365 portal, under Service Settings, User Purchasing. Use Group policy to block apps in the Office desktop applications, as well as to limit users to apps in a trusted catalog.
The Store button can be removed from the ribbon using GPO.
