Those keys are mostly ‘volume keys’ which are meant for devs. Some people sign up as devs and pay some joining fees and in return they get lots of Office keys and sell it on their website. You can’t use those product keys if you want to use Office on a different device as it’ll not bind to your MS account or can’t be activated on a different machine. You need to buy another key to use it on a different machine.

Doesn’t matter if the game is on Steam or on Epic if it’s a shit game.
