Solution 1Recommended

Verify Your Subscription Status and Re-sign In

Check if your subscription is active online and refresh your login credentials within the Office app to restore editing permissions.

License conflicts often occur if your computer has been offline for too long or if the wrong Microsoft account is currently signed in. Refreshing your session usually clears the verification block.

Check subscription online

Go to account.microsoft.com/services in your web browser and sign in to ensure your Microsoft 365 subscription is currently active.

2
Open account settings

Open any Office application like Word or Excel, and navigate to File > Account from the main interface.

Sign out

Under the User Information section, click 'Sign out' and confirm the prompt to remove the current session.

4
Sign back in

Click 'Sign in' and enter the email and password associated with your active Microsoft 365 subscription to re-verify the license.

Frequently Asked Questions

Why does Word become read-only when my subscription can't be verified?

Microsoft 365 requires periodic internet checks to confirm your subscription is active. If it cannot connect to the servers for an extended period, it enters a reduced functionality mode, making documents read-only to prevent unauthorized usage.

Can I use Microsoft 365 offline indefinitely?

No, you must connect to the internet at least once every 31 days. If you stay offline longer than that, your Office applications will display the 'Couldn't Verify Subscription' error and disable editing features.

What if I have multiple Microsoft accounts on my PC?

Conflicting Microsoft accounts can cause license verification issues. Go to File > Account in any Office app, sign out of all accounts, and sign back in exclusively with the email address linked to your active Microsoft 365 subscription.
