Microsoft has posted a free trial of Office 2007 Enterprise, the corporate edition of the new productivity suite, for a tryout by developers and IT professionals.

Office 2007 applications will run in full-feature mode for approximately 60 days, said Microsoft, a time span similar to the other Office 2007 trials that have been available on the Microsoft's Web site since Dec. 1. Registration keys must be obtained by registering using either a developer or IT professional form, also available online.

At the end of the trial run, Office 2007 Enterprise will downgrade to a crippled edition that bars users from creating, changing, or saving documents and files. Users will still be able to view and print documents, however.

The 502-Mbyte download installs Office 2007 Enterprise, which contains Word, Excel, PowerPoint, Outlook, Publisher, Access, InfoPath, Groove, OneNote, and Communicator. Non-trial copies of the Enterprise suite, a new addition to the Office line, are available only to volume license customers.

Office 2007 Enterprise's trial can be downloaded from the Microsoft site.
