Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello, thank you for reaching out to Microsoft Q&A.
May I know which edition of Microsoft Office you purchased? For example, do you have a product key for Office Home 2024, Office 365 (1-year subscription), or a different edition?
You are redeeming the product key from the official Microsoft website, correct?

- Copy and paste this link in a private browsing tab.
- Click 'Get started' and then enter your 25-character product key.
- Enter the Microsoft account you want to register the product with.
See if you can successfully redeem the Product key into your account. If it is successful, you should see the license under your Microsoft account here on the Services & Subscriptions page-
