Unlike non-subscription version of Office 2010, subscription flavors of the productivity suite require not only the initial activation, but also subsequent reactivations for the entire duration of the license.
Microsoft will be offering Office Professional Plus 2010 as a part of its Cloud productivity offering Office 365, and in tune with the service-based approach, the Office 2010 variant will only be available to customers as long as they pay the company a subscription.
“During the installation process, Office Professional Plus will automatically check the licensing and activate the product,” Microsoft informed.
“The license assigned to Office Professional Plus subscribers is valid for 30 days. The Office Subscription Agent evaluates the subscription once a month. If the subscription is still valid, the product is reactivated for another 30 days.” More »
