I have seen i few deals pop up on this site advertising Microsoft office one time purchases for pennies compared to offical licenses. Reading the comments I have understood that most of these deals are for key which were supposed to be sold with hardware.
I understand buying these key has a risk of being scammed by the seller and of a future ban by Microsoft but what other downside is there to using these. I think i remember a few years ago looking into these cheap keys and someone in the comments was saying that they can be organisation keys which gives the seller access to all your documents. Is this the case for keys activated through the offical Microsoft store and bound to your Microsoft account?
e.g I am looking at this deal https://www.ozbargain.com.au/node/599118 . Where the seller states activation is done through https://setup.office.com/
Any other risks involved with these keys which I am not seeing?
If you wouldn't recommend this method, what is the best method to acquire office or is it best to just buy at retail price?
I'd say grab a Microsoft 365 subscription when it is on sale or under the home use program from your employer if they offer it. You can stack subscriptions up to 5 years. You always get the latest features and comes with 1TB storage included on OneDrive. Plus it's all legit.
