Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Office Pro Plus 2024 is a volume licence version of Office used by large organizations, it is not a genuine consumer licence, I am sorry for the bad news, but that licence will automatically deactivate after some time and you will not be able to reactivate that licence, it is always best to purchase an Office licence directly form Microsoft, that licence is then associated to your Microsoft account as a digital licence and you can re-install Office anytime you need to.
I know those cheap licences sold online look like a good deal at the time, but after they deactivate, it is just a waste of your money.
