Solution 1Recommended

Check the Services & Subscriptions Section

Office 2021 is a one-time purchase, so it appears in a different section of your account than recurring Microsoft 365 subscriptions.

Office Professional Plus 2021 is a perpetual, one-time purchase rather than a Microsoft 365 subscription. Because there are no recurring billing charges attached to it, Microsoft categorizes it as a 'Service' or 'Product' rather than a standard active 'Subscription'.

1
Navigate to the Microsoft Account portal

Open your web browser and go to the official Microsoft account login page (account.microsoft.com).

2
Sign in with the correct account

Log in using the email address and password associated with the account you used to redeem your Office 2021 product key.

3
Access Services and Subscriptions

Click on the 'Services & subscriptions' tab in the top navigation menu. Scroll past the active subscriptions area to find the 'Products you've purchased' section. Your Office Professional Plus 2021 license will be listed here, along with an 'Install' button.

Frequently Asked Questions

What is the difference between Office Professional Plus 2021 and Microsoft 365?

Office Professional Plus 2021 is a perpetual product, meaning you pay once and own the software forever on a single computer. Microsoft 365 is a subscription service that requires ongoing monthly or annual payments but includes continuous feature updates and cloud storage.

Where can I find my Office 2021 product key after installing?

Once a product key is redeemed to a Microsoft account, it is converted into a digital license. Microsoft does not display the full 25-character product key inside your account dashboard for security reasons. Your license is securely tied to your email address.

Can I transfer my Office 2021 one-time purchase to a new computer?

Yes, depending on your local software license terms, you can generally transfer a retail Office 2021 license to a new computer. You must uninstall it from the original machine first, then log into your Microsoft account on the new computer, go to 'Services & subscriptions', and click 'Install'.
