Yes, I forgot how to do it too.. so here are my notes for doing it.
If you are missing the KMS keys from the MVLSC for office 2016 then you need to contact Microsoft at KMSADD@microsoft.com to get your MAK key converted to KMS.
If you want to call them, use this number: (866) 230-0560
Here is the format of my email to them:
Update: They now have a web form for you to fill out to request KMS keys:
------------ Start email Template ------------
I need KMS keys generated for Office 2016 please.
Here is my Office 2016 with SA License agreement:
License ID: XXX
Parent Program: XXX
------------ End email Template ------------
When you add your Office 2016 KMS keys it will cover everything office including Visio and Project.
When you get your KMS keys, then you are ready to download the update…
