There are two ways to activate computers by using MAK:
After Office is activated, no re-activation is required unless the hardware changes significantly. Each Office activation that uses MAK counts toward the activation limit. MAK activation requires that a MAK is installed on a client computer and instructs that computer to activate itself against those services.Įach MAK has a predetermined number of allowed activations and is based on your volume licensing agreement.
Multiple Activation Key (MAK) activation is used for one-time activation through Microsoft-hosted activation services, either via the internet or by telephone. Applies to: Volume licensed versions of Office LTSC 2021, Office 2019, and Office 2016 (including Project and Visio)
