Google has announced global availability of Google Cloud Connect for Microsoft Office, which was launched as beta in 2010.
Google Cloud Connect for Microsoft Office brings collaborative multi-person editing to the familiar Microsoft® Office experience. You can share, backup, and simultaneously edit Microsoft Word, PowerPoint®, and Excel® documents with coworkers.
The plug-in syncs to Google’s cloud so that multiple people can make changes to the same file. A Cloud Connect toolbar is displayed in Microsoft Office that allows users to sync their version of the file with an online version in Google Docs.
Requirements:
Windows XP with .NET Framework 2.0, Windows Vista, or Windows 7
Microsoft Office 2003, Office 2007, or Office 2010
Google Cloud Connect is not available for Mac OS X
