You are required to activate your deployment of Volume License editions of Microsoft Office 2010. This includes Microsoft Office Professional Plus 2010, Microsoft Project 2010, and Microsoft Visio 2010. Activation reduces the possibility of deploying counterfeit software, which can include malware, viruses, and other security risks.

This information applies to volume-licensed editions of Office 2010. It does not apply to Office Professional Plus for Office 365, which is licensed through subscription.

Multiple Activation Key (MAK) activation occurs directly with Microsoft (different from Key Management Service [KMS], in which activation occurs through a local host server). If your organization has 6 to 49 computers that need to active Office 2010, we recommend that you use MAK proxy activations managed through Volume Activation Management Tool (VAMT) ( for all computers that can connect to a MAK proxy server. For those computers that are isolated from the corporate network or the Internet, we recommend that you use MAK independent activation through the telephone.

The following is an example of a network that can use MAK proxy activation.

Contoso, Ltd. has 15 desktop computers and 10 portable computers in their single office. The desktop computers are connected to the Internet, and the portable computers are isolated from all networks. The solution is to use VAMT ( to manage the MAK proxy activation of the desktop computers through the Internet, while you independently activate the portable computers through the telephone.
