Solution 1Recommended

Verify the Associated Microsoft Account

Confirm that you are signing into Word with the exact Microsoft account where your subscription was purchased or redeemed.

A common cause of this error is having multiple Microsoft accounts and signing into the desktop application with an account that is not linked to your active Microsoft 365 subscription.

1
Visit Microsoft Services

Open your web browser and navigate to https://account.microsoft.com/services/.

2
Sign In

Log in using the email address you are attempting to use in Microsoft Word.

3
Check Subscription Status

Look under the 'Services & subscriptions' section. If your Microsoft 365 subscription is not listed, sign out and log back in using an alternative email address.

4
Sign Into Office

Once you locate the account holding the active subscription, open Microsoft Word and sign in with that specific email address.

Frequently Asked Questions

Why does Microsoft 365 say I don't have a subscription after entering my product key?

This typically occurs if the product key was redeemed on a different Microsoft account than the one you are currently signed into, or if your local application is caching old license data.

Can I transfer my Microsoft 365 subscription to a different account?

No, Microsoft 365 subscriptions cannot be transferred between accounts manually. You must log into your Office apps using the account originally used for the purchase or redemption.

Does reinstalling Microsoft 365 fix the account mismatch error?

A standard reinstall rarely fixes account mismatch errors because old license data may remain on your system. For Mac users, using the official License Removal Tool is much more effective.

How do VPNs affect Microsoft 365 activation?

VPNs can route your traffic through servers that Microsoft's security systems flag or block, preventing your application from successfully verifying your subscription status. Disabling the VPN temporarily usually resolves this.
