Question details
The user is encountering a TOKEN_NOT_FOUND error during the activation process for Microsoft Office 2019.

- Product
- Microsoft Office 2019
- Device & OS
- not provided
- Scenario
- Activating a newly purchased or installed Microsoft Office 2019 software using a product key or digital license.
- Observed behavior
- The system displays a TOKEN_NOT_FOUND error message, preventing successful activation and installation of the Office 2019 suite.
Ensure you have your 25-character Office product key handy and know the exact Microsoft account credentials used to purchase the software.
Use the Correct Purchasing Account and Remove Preinstalled Trials
The most common cause of this error is an account mismatch or a conflict with a preinstalled Microsoft 365 trial version on the device.
If your computer came with a preinstalled Microsoft 365 trial, it can interfere with a standalone Office 2019 activation. Furthermore, installing Office while signed into a different account than the one used for the purchase (such as a spouse's or family member's account) will trigger the TOKEN_NOT_FOUND error.
Go to your system's Settings, navigate to the Apps section, locate any 'Microsoft 365' or 'Office Trial' installations, and uninstall them completely.
Sign out of any incorrect Microsoft accounts currently active on your device or browser.
Navigate to setup.office.com and sign in using the exact Microsoft account that was originally used to purchase Office 2019.
Follow the on-screen prompts to redeem your 25-character product key if requested, then download and install the Office 2019 software.

Verify Product Key Accuracy
Ensure the product key entered matches your specific Office version and contains no typographical errors.

Frequently Asked Questions
Why am I getting the TOKEN_NOT_FOUND error?
This error typically occurs if the product key entered is invalid, if you are logged into the wrong Microsoft account during installation, or if there is a conflict with a preinstalled Microsoft 365 trial on your device.
Do I need to uninstall Microsoft 365 before installing Office 2019?
Yes, it is highly recommended to uninstall any preinstalled Microsoft 365 Family or Personal trial versions from your computer before attempting to activate and install Office 2019 to prevent license conflicts.
How do I know which Microsoft account to use?
You must use the exact Microsoft account that was used to purchase the Office 2019 license. Using a different account, such as a family member's account, will result in activation errors.
What should I do if my product key still doesn't work?
If you have verified the key for typos, removed trial software, and confirmed you are using the correct purchasing account, you should contact Microsoft Support directly to check the status of your product key.
