Step 1: Sign in with the right account

Please try signing in using all your personal email addresses in case you bought Office using a different email address. If you're at work or school, you may need to log in using your work or school account instead of your personal email account.

To check if your Microsoft account is associated with Office, sign in to Services & subscriptions. Your Office product or Microsoft 365 subscription should be listed there. If it's not, your email address won't work for signing in to Office.

Step 2: Check for multiple copies of Office

Activation can fail if you have multiple copies of Office installed. Let's uninstall any versions of Office you aren't using before we continue to troubleshoot.

4. Open an Office app and sign in, if prompted.

5. If Office still won't activate, try running an online repair as described in Repair an Office application to fix up the remaining install of Office. If you still can't activate, proceed to the next step.

Step 3: Check your Microsoft 365 subscription status

If you have an Microsoft 365 for home subscription, let's make sure it's still active and renew your subscription, if necessary.

If you don't have Microsoft 365, you can skip to Step 4: Troubleshoot Office activation.

• Under Microsoft Defender Firewall, switch the setting to On. If your device is connected to a network, network policy settings might prevent you from completing these steps. For more info, contact your administrator.
• To turn it off, switch the setting to Off. Turning off Windows Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access.
