When an Office 2016 volume edition client is installed, it will automatically attempt to activate via either Active Directory by using its existing domain pairing or a DNS-discoverable KMS host on your organization network.
If you want to activate volume license editions of Office 2016, Visio 2016, or Project 2016 with a KMS host or Active Directory-Based activation, you need to first install Office 2016 Volume License Pack.
