In a first for the software major, Microsoft Corp. has said that it will allow users to test the next version of Office online without having to download software. Customers can visit Microsoft's Web site to "test drive" the software from within their Web browsers.
Supported browsers for the release are Internet Explorer 6 or a later version of IE.

Applications included in the Web-based test version of Office 2007 are Microsoft Office Access 2007, Excel 2007, InfoPath 2007, OneNote 2007, Outlook 2007, Outlook 2007 with Business Contact Manager, Outlook Web Access, PowerPoint 2007, Project Professional 2007, Publisher 2007, SharePoint Designer 2007, Visio 2007, Word 2007, SharePoint Services, Project Server 2007 and SharePoint Server 2007.

Microsoft has already released two beta versions of Office 2007, and the company says that 2.5 million users so far have downloaded Beta 2, which it made available in May.

Using a test version of Office 2007 through a browser eliminates the problem of a new version of Office replacing any earlier version of Office that may have been installed. An online test version of Office could also fuel speculation that Microsoft will eventually offer the software online as a Web-based service.

Microsoft already offers a service called Office Live that offers Web-site hosting, document-management and business- management tools. It, however, does not offer worker productivity applications the way packaged software versions of Office does.

Microsoft plans to release Office 2007 to business customers before the end of the year and to consumers in January 2007.
