How to Fix Unlicensed Product Errors in Microsoft Office on Windows 10

Product: Microsoft Office
Device & OS: Windows 10
Scenario: Setting up and activating Microsoft Office after switching to a new Windows 10 device.

Solution 1Recommended

Verify Microsoft 365 License with Your Administrator

Check if your organization has assigned an active desktop application license to your account.

If you are using a work or school account, your Microsoft 365 administrator manages your app licenses. Even if you have a subscription, the specific license for desktop applications might not be assigned to your new device.

Contact your IT administrator

Reach out to your organization's Microsoft 365 administrator and request them to check your account status.

Confirm desktop app license

Ask the administrator to verify that your account is assigned an active license that specifically includes the desktop versions of Office applications.

Check expiration date

Ensure that the subscription associated with your account has not recently expired.

Verify Microsoft 365 License with Your Administrator

Administrative Access: Only users with admin privileges in the Microsoft 365 portal can view and modify assigned licenses for organizational accounts.

Solution 2

Reconnect Your Work or School Account

Ensure your Microsoft account is properly synced with your Windows 10 settings to authenticate Office.

Solution 3

Check for Duplicate Office Installations

Remove conflicting versions of Microsoft Office installed on your device.

Frequently Asked Questions

Why does Microsoft Office say Unlicensed Product even though I paid for a subscription?

This can happen due to poor internet connectivity blocking server communication, having duplicate versions of Office installed, or your work/school account failing to sync properly within your Windows 10 settings.

Can I still use Microsoft Word if my product is unlicensed?

When Office is unlicensed, it enters reduced functionality mode. You will be able to open and view your documents, but you cannot edit them or create new ones until the license is reactivated.

How do I check which account is linked to my Microsoft Office license?

Open any Office application, such as Word, click on 'File', and select 'Account' at the bottom left. Under 'Product Information', you will see the email address associated with your current license.

Will uninstalling and reinstalling Office fix the unlicensed error?

Reinstalling can fix corrupted files, but if the issue is a missing license assignment from your admin or a disconnected Windows 10 work account, reinstalling will not resolve the root cause of the error.
