If you need to change the activation limit of your MAK up to double the amount of activations originally allocated, the call center can help with these activations during the phone call. If the amount of activations needed is more, the Call Center representative will guide you through the steps needed to take part in the MAK exception process (MAKADD).
As part of the exception process, you need to provide the following information to Microsoft via an e-mail address provided to you by the Activation Call Center:
Organization name
Agreement number, or license and authorization numbers, associated with the key
Requester’s name, phone number, and e-mail address (must match the Microsoft Authorized Contact List as defined by your organization)
Product (e.g. Windows Vista, Windows Server 2008 Standard)
Last five digits of product key
Number of activations requested
Business reason for request
Required date


The MAKADD support team follows up with the requester to address any specific questions or concerns. All MAKADD requests have a five business day response time, though the process may take longer if Microsoft is waiting for customer information.

As an added security measure, all requests are verified through the customer “Notices Correspondent” for approval prior to any increases being granted. Please add them as part of the e-mail request to expedite the process. Please note that non-English requests may take longer than five business days for response.
