However, encountering the dreaded “Unlicensed Product” error can grind your efficiency to a halt. If you’re reading this, chances are you’re dealing with the issue and searching for answers.
Fear not!
This guide will walk you through everything you need to know about resolving the “Unlicensed Product” error, helping you get back on track with minimal frustration.
Understanding the “Unlicensed Product” Error
Before we look at the solutions, it’s important to understand what this error signifies. The “Unlicensed Product” message indicates that Microsoft Office cannot verify your license. Without a valid license, the software operates in a reduced functionality mode, preventing you from creating or editing documents.
Common Causes of the Error
- Activation Issues: A product key wasn’t entered correctly, or the activation process wasn’t completed.
- Account Problems: Log in with an incorrect Microsoft account.
- Connectivity Issues: A poor or unstable internet connection prevents communication with Microsoft’s servers.
- Conflicting Software or Corruption: Corrupted files or interference from other applications.
- Licensing Limitations: Using the same product key on too many devices.
Prerequisites for Troubleshooting
To ensure a smooth resolution process, gather the following essentials:
- A Stable Internet Connection: Reliable access to the web is critical for license verification.
- Microsoft Account Credentials: Ensure you have the email and password tied to your Office purchase.
- Product Key or Digital License: Locate your product key (typically in your purchase confirmation email).
Before proceeding, it’s wise to save and back up your work to avoid losing any progress.
Common Causes and Solutions

If Office repeatedly prompts you for a product key, there may be an issue with the one you’re using or the account you’re logged into.

5. Licensing Server Issues
Sometimes, the problem is out of your control. Microsoft’s servers might be down, causing activation errors.

- Visita el Microsoft Office Service Status page to check for reported outages.
