Microsoft Office 2007 will be released later this year and it will arrive in seven editions.
The new Enterprise edition features Groove 2007, which adds collaboration tools Microsoft gained when it acquired Groove Networks last year. It also includes Office Communicator, and has built-in support for enterprise content management, electronic forms, and information rights and policy capabilities.
Meanwhile, a Professional Plus edition replaces the Professional Enterprise version of Office 2003. This version does not include Groove 2007 or OneNote 2007, however.
