Microsoft have announced a beta version of Harmony for Google Docs.

Harmony provides a sidebar for Microsoft Outlook that allows users to send document links, instead of email attachments.

Users can search document contents on Google Docs from the Harmony search box; drag a Google document from the sidebar to automatically generate links inside their emails; and save Google documents in Microsoft Office format.

Harmony requires Microsoft Outlook 2007. It can be downloaded for free from the Harmony website.
