Retrieve Product Key via Workplace Discount Program

If you purchased Office Professional Plus through your employer, you can safely recover your product key from your official Microsoft order history.

Office Professional Plus 2016 is generally a volume-licensed edition and is rarely sold directly to individual consumers. The most common legitimate way a consumer would have this edition is through the Microsoft Workplace Discount Program (formerly Home Use Program).

Visit the Workplace Discount Program page

Open your web browser and navigate to the official Microsoft Workplace Discount Program order history page at: https://www.microsoft.com/en-us/workplace-discount-program/order-history.

Locate your product key

Find your Office Professional Plus 2016 purchase in the order history list. Your 25-character product key will be displayed next to the order details.

Activate Office

Open any Office application, such as Word, and enter the product key when prompted by the activation wizard to complete the process.

Important Note on Software Sources: Be cautious with unknown download sources. If you did not obtain your copy through an official workplace program, there is a significant possibility that the download website was fraudulent or unauthorized.
