Verify Your Office License and Microsoft Account

Check your Microsoft account to confirm the exact license type associated with your purchase and ensure it is still active.

A perpetual Office license and a Microsoft 365 subscription have different terms. Sometimes, users inadvertently log into a different account or have a conflicting trial subscription installed.

Look through your active products to determine if you own a perpetual license (such as Office 2019) or if the account indicates that a Microsoft 365 subscription is required.

Conflicting Installations: If you see your perpetual license listed but are still being prompted for Microsoft 365, check your computer's installed programs to ensure a pre-installed Microsoft 365 trial isn't causing a conflict.

Frequently Asked Questions

Does a perpetual Microsoft Office license expire?

No, a legitimate perpetual Office license (like Office 2016 or 2019) does not expire. However, if Microsoft detects that the key was counterfeit, illegally distributed, or tied to a restricted volume license, they may revoke and disable it.

Why is Microsoft 365 prompting me to pay when I already bought Office?

You might have both your older perpetual Office version and a trial version of Microsoft 365 installed on your computer simultaneously. Uninstalling the Microsoft 365 trial version from your system settings often resolves this conflict.

Can I still use my older Office applications offline without activating Microsoft 365?

If your perpetual license is valid, you can use it offline indefinitely. But if the software prompts for Microsoft 365 activation when offline, it indicates a failed license validation that will restrict your editing capabilities until resolved.

How do I know if I was sold a counterfeit Office license?

If you purchased an incredibly cheap license key from a third-party marketplace rather than an official retailer, it may be a volume license or a counterfeit key. Microsoft periodically scans and deactivates these unauthorized keys.
