Office 2016 KMS Keys Missing – How To Get Them
You bought a Volume License for Office 2016. You log in to your VLSC site and see only MAK keys. You still see KMS keys for prior versions of Office but not 2016.
Call Microsoft. They are hiding these keys for some reason. You’ll need to provide the agreement number listed in your VLSC site so have that open when you call.
866-230-0560 option 4, option 1 (main number listed on the VLSC site)
