How to Fix Excel Product Deactivated with an Active Microsoft 365 License
Question details
The user is unable to use Microsoft Excel because it displays a Product Deactivated message, even though their Microsoft 365 license is currently active.
- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Trying to edit or create spreadsheets in Excel but being blocked by an incorrect activation status.
- Observed behavior
- Excel shows a Product Deactivated warning, which is caused by outdated stored credentials, expired authentication tokens, or disconnected work/school accounts.
Ensure you have your Microsoft 365 account email and password ready, and verify with your IT administrator that your license is actively assigned to your account.
Clear Outdated Credentials and Reconnect Account
Removing old Microsoft credentials from Windows and reconnecting your account clears corrupted authentication tokens.
Often, Excel relies on cached authentication data. When this data expires or conflicts with a renewed license, the application will falsely report that the product is deactivated. Clearing this cache forces Excel to retrieve the correct, active license status.
Open Excel, click on your account profile in the top right corner, select Sign Out, and then completely close all running Office applications.
Click the Start menu, search for 'Credential Manager', and open it. Click on 'Windows Credentials' and remove any entries related to Microsoft Office or Microsoft 365.
Navigate to Windows Settings > Accounts > Access work or school. Find your connected Microsoft 365 account, click Disconnect, and then click Connect to sign in again.
Restart your computer, launch Excel, and sign in with your active Microsoft 365 credentials. The activation error should now be resolved.
Use Microsoft's Activation Reset Tool
If manual credential clearing fails, you can use Microsoft's official script to force an activation state reset.
Switch to WPS Office to Avoid Activation Hassles
If you are frequently locked out of your spreadsheets due to Microsoft 365 activation errors, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative without complex license management issues.
- 1. Download the installer: Visit the official WPS Office website and download the free software for your operating system.
- 2. Install and launch: Run the installer, complete the quick setup, and open WPS Spreadsheets.
- 3. Open your files instantly: Drag and drop your existing Excel files into the workspace to continue editing without any activation barriers.
Frequently Asked Questions
Why does Excel say my product is deactivated when my subscription is active?
This happens when Windows caches old authentication tokens. Even though your license is active on Microsoft's servers, Excel is attempting to authenticate using outdated, stored local data.
Will I lose my Excel files if I remove Microsoft credentials?
No. Removing credentials from the Windows Credential Manager only clears login information, forcing Excel to ask for your password again. Your locally saved documents and OneDrive files remain completely safe.
What should I do if clearing credentials doesn't fix the activation error?
Try disconnecting and reconnecting your account via Windows Settings > Accounts > Access work or school. If that fails, contact your IT administrator to ensure your specific Microsoft 365 license hasn't been unassigned by mistake.
