Microsoft Corp. announced on Monday that it has finalized development on its Office 2007 productivity software, and expects to release the new package to corporate customers by the end of the month.

We’ve crossed the development finish line, and the team deserves to celebrate, said Jeff Raikes, president of the Microsoft Business Division. The 2007 Microsoft Office system RTM completes the most significant improvements to the products in more than a decade.

The Office 2007 package will include updated versions of its popular Word editing software, Excel spreadsheet tool, PowerPoint presentation software, as well as other office related software.

Microsoft will also make the new Windows Vista operating system and 2007 Exchange e-mail server available to business customers on the same day, and said all the products will become widely available to consumers in early 2007.
