Microsoft Office add-ins add a wide variety of features to Microsoft's Office. Most are designed to add functionality to specific programs like Microsoft Word, Excel or Outlook. The Office Live Workspace add-in is an official add-in that is being developed by Microsoft. It provides Microsoft Office users with the ability to upload their documents to the Microsoft Office Live Workspace on the Internet.
This does mean that an account at Microsoft Office Live Workspace is required before the add-in can be used. The service is free on the other hand and it takes only a few seconds to signup for it. Windows Live account users can use their account to signup for Microsoft Office Live Workspace. The service is currently in beta and provides access to 5 Gigabytes of storage space for Microsoft Word, Excel and PowerPoint documents that can also be edited on the website.
Office 2007 users find the option to upload their documents to the Microsoft Office Live Workspace and to open documents from the online storage space under the Microsoft Office button in Word, Excel and PowerPoint.
Office 2003 and XP users get a new Office Live toolbar that provides access to three buttons that offer the functionality to open documents that are stored at Microsoft Office Live Workspace, save documents so that they are stored online and to open the Office Live Workspace website.
The Office Live Add-in itself is compatible with Microsoft Office 2007, Office 2003 and Office XP.
Update: Please note that the add-in is no longer provided by Microsoft. This has certainly something to do with the company's move away from Windows Live to SkyDrive which is the new remote storage solution. What you can do is this. Download and install SkyDrive, it is free to use, and use the Save As and Load options in Office to save and load documents from SkyDrive instead. The program creates a folder on your computer during installation that gets automatically synchronized with the online storage whenever you have an Internet connection.
