Frequently Asked Questions

Why does Word say Unlicensed Product when I have an active license?

This usually happens if Office cannot verify your license. Common causes include being signed in with the wrong user account, a firewall blocking Microsoft's activation servers, or system clock inconsistencies.

Can another Windows user profile on the same PC use my Office 2021 license?

Office 2021 is generally licensed per device, but the software still requires verification. A secondary Windows user profile may need to sign in to the Office apps using the primary Microsoft account tied to the purchase to remove the 'Unregistered' restriction.

How do I manually check if my Office 2021 is activated?

Open any Office application like Word, click on 'File', and select 'Account'. Under the 'Product Information' section on the right side, it will explicitly state if the product is 'Product Activated' or if it requires attention.
