I then logged in using my Microsoft account. I haven't heard about problems like that from 'cheap' key online stores.Īfter I bought the Product Key for Office Professional Plus 2019 I was told to go to the website ' '. The main difference that I see is that keys sold on auctions are usually locked after a year or some more when there are too many activations registered on too many various computers. MS is hunting them, so I don't get how some legal-looking stores, with ads around the web, do the same on a larger scale. The same things do people buying 'infinite' (in real it's 50 or 100 right now, but used to be infinite) activation keys for corporations and selling them multiple times on auctions for ~$10-20. In theory selling these versions shouldn't be legal. On the other hand I'm not sure how MS sees these cheap key stores selling their corporate edition products 90% cheaper than in distribution (I work in distribution and they cost more than OEM/Box versions).

Alternative way is to add a product key to your MS account (the same where you activate other MS products/subscriptions like XBOX, Office 365 and others) and then you have download link in the subscriptions tab. I did that with Office 2021 Pro Plus from a 'cheap' keys site. As I said, when you have a product key, then you can use retail downloader from MS site (my last post) and it will automatically generate you link to your version, but you have to be logged onto your MS account as all new licenses are signed to user's account (and activation is signed to a PC).
