Microsoft Education Labs has a free Office Addon for Moodle. This addon allows teachers or the owner of a Moodle course to upload documents to their course and access Moodle documents from within Office. Once the addon is installed to Office two items are added to the file menu: Open from Moodle, and Save to Moodle.

 The user configures the address of their Moodle server and logs in with their Moodle login. After this the user can access Moodle files from Office. 

 The addon works with Office 2003 and 2007 and Moodle 1.8.x and 1.9.x. The My Courses should be installed for the addon to work. No additional Moodle modules are required for the addon to work.
