- Product
- Microsoft 365 Apps
- Device & OS
- Windows 11
- Scenario
- Activating and signing into a shared Microsoft 365 Family subscription.
- Observed behavior
- Office applications report that they are unlicensed, and attempting to activate or sign in produces a network message or error.
Ensure that your Windows 11 device has an active internet connection and verify that you are logging in with the exact Microsoft account associated with the shared subscription.
Confirm the Subscription Sharing Invitation
Verify that the Microsoft 365 Family owner shared the subscription correctly and that you have fully accepted the invitation.
Contact the Microsoft 365 Family subscription owner to confirm they shared the subscription with your correct email address.
Open your email inbox, locate the sharing invitation email from Microsoft, and click the provided link to accept it.
Launch any Microsoft 365 app, such as Word, and sign in using the Microsoft account that successfully accepted the invitation.

- 1. Download the Installer: Visit the official WPS Office website to download the free setup file.

- 3. Open Your Documents: Start using WPS Office immediately to open, edit, and save your existing Office files without activation issues.
Frequently Asked Questions
Why does my Microsoft 365 app say 'Unlicensed Product'?
This error occurs if your subscription has expired, you are signed in with the wrong account, or there is a communication error between your device and Microsoft's activation servers.
What happens if I don't activate Microsoft 365?
If you do not activate the software, Microsoft 365 apps will enter reduced functionality mode. You will be able to open and print documents, but you will not be able to edit them or create new ones.
What is the difference between Quick Repair and Online Repair in Windows?
Quick Repair runs fast and fixes most issues offline by replacing corrupted files. Online Repair takes longer and requires an internet connection because it completely uninstalls and reinstalls the Office suite.
How do I verify my Microsoft 365 activation status?
You can verify your activation status by signing into your Microsoft account online and checking the 'Services & subscriptions' page to see if your Microsoft 365 Family plan is active.
