Microsoft online services

Navigating the plethora of Microsoft's online solutions can be confusing. Here's a high-level overview to help you choose.

Document-centric services

Office Live Workspace

Microsoft’s first try at online editing of documents, Office Live Workspace was free for all kinds of users. The service has been discontinued in January 2011 and was replaced with “Office Web Apps on SkyDrive”.

Office Web Apps on SkyDrive

Targeted towards home users and students, this free solution allows users to view and edit documents through most web browsers, share them and collaborate on Office documents with others.

Documents from SkyDrive can easily be opened in the full versions of Word, Excel and PowerPoint, if the user has them installed, but purchasing these applications is not required to use Office Web Apps on SkyDrive.

Go to Office Web Apps on SkyDrive

Like Office Web Apps on SkyDrive, lets home users create and share Office documents for free and through a web browser. The main difference is a deep integration of with Facebook, making a more attractive solution for social collaboration with Facebook friends, classmates and coworkers.
