but it will need activation within a certain 'grace' period otherwise much of its features will be disabled.

You can activate over the telephone;

"Office 2010 Product key activation by telephone

You can also choose to telephone an activation Center and activate your office 2010 product, with the help of a customer service representative. Telephone numbers vary by product license and country or region. In step 2 of the Activation Wizard, use the telephone number provided to call the Microsoft Activation Center."

I hope that helps.
