Microsoft Office 2010 is now available for free download in Beta form.

The download is for Office Professional Plus 2010, a feature-laden edition that will be available only to enterprises and organizations that purchase licences in volume when the final suite ships next year.

Office Professional Plus includes Word, Excel, Outlook, PowerPoint, OneNote, Access, Publisher, InfoPath, SharePoint Workspace - formerly called Groove - and Communicator.

The 32-bit version of the English-language suite runs 685MB, while the 64-bit edition tips the scales at 750MB.

Users who download Office 2010 Beta are provided with a 25-character product key to activate the preview.

The updated Office will be available in two separate formats: a traditional PC-based edition and a completely web-based version. Both products are expected to be released in the first half of 2010.

Microsoft Office 2010 review

So far, Microsoft has offered a preview of its next desktop suite only to a relatively small group of testers. It has also opened the online edition, Office Web Apps, to a similar preview.

Office Web Apps includes lightweight versions of Word, Excel and PowerPoint and will be made available to millions free of charge in the first half of next year, the only timetable Microsoft has set for Office 2010's ship date.

That suite, which runs on Windows Mobile 6.5-based phones, includes scaled-back versions of Word, Excel, PowerPoint, OneNote and new SharePoint Workspace Mobile 2010. It can be downloaded from the Windows Marketplace for Mobile, DelBene said.

DelBene did not set a timetable for the release of Office 2010, keeping to the company line that the suite will ship in the first half of next year.
