This policy setting allows you to specify Token Activation as the only volume activation method for volume editions of Office. This policy setting only applies if a Token Activation Issuance License has been installed on the computer.

If you disable or do not configure this policy setting, Key Management Service (KMS) or Token Activation may be used as methods to activate Office.
