Solution 1Recommended

Sign Out and Re-authenticate Your Microsoft Account

Re-authenticating the Microsoft account associated with your Office license can restore the missing activation token.

Hardware changes, system updates, or corrupted local files can sometimes cause a valid Office installation to lose its activation status. End of support for Office 2013 does not invalidate your lifetime license.

By signing in online and refreshing the account connection inside the application, you force Office to verify your license again.

1
Verify your license online

Open a web browser, go to account.microsoft.com/services, and sign in with the Microsoft account linked to your Office purchase to ensure the license is still active on your account.

2
Sign out of the Office application

Open Word or any other Office 2013 application. Click on 'File' in the top-left corner, select 'Account', and click 'Sign out' under the User Information section.

3
Sign back in to reactivate

Restart the Office application, return to 'File' > 'Account', and click 'Sign In'. Enter your Microsoft account credentials to restore the license.

Sign Out and Re-authenticate Your Microsoft Account
Check Your Local Account: If you are using a local computer account instead of a Microsoft account, you may need to enter your 25-character product key directly instead of signing in.

Frequently Asked Questions

Does Office 2013 stop working completely after its end of support?

No, Office 2013 will continue to function normally. 'End of support' simply means you will no longer receive security updates, bug fixes, or technical support from Microsoft. It does not deactivate your valid lifetime license.

Why did my Office 2013 suddenly lose its activation status?

This can happen due to major Windows operating system updates, significant hardware changes (such as replacing a hard drive or motherboard), or because the local license files on your computer became corrupted.

Can I still use my Office 2013 product key to reactivate?

Yes. If you have the original 25-character product key, or if the license is digitally tied to your Microsoft account, you can use either method to reactivate your software.

What should I do if my Microsoft account says no license is found?

Ensure you are signing in with the exact email address used when you originally purchased or registered Office 2013. If you used a product key without linking it to an email, you must use the original product key to activate.
