Microsoft Store für Unternehmen schließt am 14. April 2021

Starting April 14, 2021, all apps that charge a base price above free will no longer be available to buy in the Microsoft Store for Business and Education. If you’ve already bought a paid app, you can still use it, but no new purchases will be possible from businessstore.microsoft.com or educationstore.microsoft.com. Also, you won’t be able to buy additional licenses for apps you already bought. You can still assign and reassign licenses for apps that you already own and use the private store. Apps with a base price of “free” will still be available. This change doesn’t impact apps in the Microsoft Store on Windows 10.
Also starting April 14, 2021, you must sign in with your Azure Active Directory (Azure AD) account before you browse Microsoft Store for Business and Education.
