I’m trying to activate Office 2016 and found a product key online that claims to work. Has anyone used this specific method or key to activate Office 2016? I want to make sure I’m using a legit key and that I won’t encounter any problems later.

Here’s the guide I found: Office 2016 Product Key. Does anyone know if this activation method is reliable? Is it easy to follow, or should I look for a different option?
