Office 2010 Reaches RTM!

RTM is the final engineering milestone of a product release and Microsoft engineering team has poured their heart and soul into reaching this milestone.
Volume License customers with active Software Assurance (SA) on these products will be one of the first to receive the 2010 set of products. They will be able to download the products in English via the Volume Licensing Service Center starting April 27. Customers without SA will be able to purchase the new products through Volume Licensing from Microsoft partners starting May 1.
