Processi in Microsoft 365 per configurare app di Office, riscattare chiavi del prodotto e attivare le licenze.
Hello, thank you for reaching out to Microsoft Q&A.
Did you purchase the Product key from a third-party retailer?
Support for Office Home & Business 2019 for Mac has already ended. Therefore, older product keys might not work when you try to redeem them through Microsoft’s servers. I recommend contacting the seller directly and exchanging it for the latest version of Office, such as Home & Business 2024 or an Office 365 subscription.
