Is there anyone who has the product key for Microsoft Office 365? I need some info.
BTW what is the question? You need to ask us about what you are trying to find out. Is it a forgotten key or what. Answer ASAP.
You have to take advantage of the official support in order to get information related to the way product activation works in 365. As far as I know, the product key will be used to activate the software on the website of the developer.
