Microsoft Unlicensed Product - Activation Failed? Fix Now

Part 1: What Does Microsoft Unlicensed Product Mean?

The message Microsoft Unlicensed Product means that Office can’t verify your license. This happens in Microsoft Word, Excel, and other apps. You may see messages like Microsoft Word Unlicensed Product or Excel Unlicensed Product, and the app might switch to view-only mode.

Common reasons this happens:

• Microsoft Office product activation failed due to internet or login problems.
• Wrong microsoft account signed in.
• The license expired or was removed from your account.
• You installed multiple Office versions that are clashing.
• Error code 0x426-0x0 (Office services malfunction)

When Microsoft 365 shows unlicensed product, it causes big problems, especially if you’re working on documents daily. Let’s look at the symptoms next.

When Microsoft Office loses its license status, it begins to show specific signs that impact your ability to work. Below are the most common symptoms users face when dealing with the Microsoft unlicensed product error in Office apps.

1. Microsoft Word Unlicensed Product

When this happens, you'll see "Unlicensed Product" in the title bar. You can open Word files, but you can’t type, save, or change anything.

2. Excel Unlicensed Product

Excel behaves the same way. It shows the alert and limits you to view-only. You can’t edit sheets, use formulas, or save updates.

3. Microsoft 365 Showing Unlicensed Product

If your whole Microsoft 365 account shows the unlicensed error, every Office app—Word, Excel, PowerPoint will stop working properly. It blocks productivity for students, workers, and businesses.

This specific error pops up when Office apps crash or fail to start. It’s often tied to broken services or failed updates.
