Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
- May I please know whether the product key you purchased is for a Microsoft 365 Personal or Microsoft 365 Family subscription?
- Also, did you receive the product key on a physical Microsoft 365 key card from a third-party seller, or did the seller send the product key to you via email?
Before redeeming the key again, ensure the Office 365 1-Year subscription is already associated with your Microsoft account.
- You can sign in to the Services & Subscriptions page to check that - https://account.microsoft.com/services
If the subscription is not associated with your account,
- Connect your PC to another Wi-Fi network, such as a mobile hotspot network.
- Then, use another/new web browser.
- Go to https://setup.office.com/redeem/enter-key to redeem the key successfully.
You can also use the mobile web browser on your smartphone and then visit the link above to redeem the key.
