Works! These guys are legit!

There's no need to set up a Microsoft account to use the Cd Key Global. Just download the Office 2016 Pro Plus Retail image in your language. Massgrave(dot)dev has the direct links to the MS servers for the official images. They are labelled ProPlusRetail.img and include both the 32-bit and 64-bit versions. Go to the section titled Office C2R Installers and click on the Office 2016 tab. Look for your language and the line item ProPlusRetail. Click on the third link to download the official IMG file. Once downloaded, mount the IMG file in Windows (File) Explorer and run Setup. After installation run one of the Office apps and you'll be asked to enter the license key.
