Microsoft announced that starting today, people will be able to view and share Office docs on Facebook. So now, whether you're in Hotmail, Office 365, or Facebook, you've got access to all your Office docs.
Facebook's new messaging platform integrates the Office Web Apps to enable Facebook users to view Microsoft Word, Excel, and PowerPoint documents with just one click.
When you receive a Word, Excel, or PowerPoint document attachment in your Facebook message, click "View on Office.com" to view it in the browser in high fidelity via OWA or click "Download" to download the file to your computer.
Clicking "View on Office.com" opens a new browser tab with document in the Word/Excel/PowerPoint Web App.
You can also check out OWA Windows Live here, which delivers browser-based editing of Office documents in addition to viewing, and also works with Live SkyDrive to collaborate on group projects like this.
