Microsoft Office 2019 sealed key card for lifetime 1 user (windows) New Listing 2019 MICROSOFT OFFICE PRO PLUS 32/64 BIT | Original Activation Key Lifetime 1-PC. How did you get Pro Plus? If you got it through the HUP, Home Use Program, from your work, fine. If you bought it off the internet (probably for less than $100), it is 99.44% likely to be an illegally resold "volume" license. You stand the risk of MS becoming aware of what the vendor is doing then MS will disable the keys and you will be out of ipfpsk.
