This feature uses online viewer provided directly by Microsoft website, that's a free service which doesn't require any registration (at the moment of writing this documentation page); you can read more on this at Microsoft Office Blogs page. In terms of WebMail, it allows for viewing supported documents attached to email messages; in WebMail Pro and Aurora, it also works within Files module.
