One is for the web apps that can open, create, edit Microsoft Office Documents in your web browser. The other is for an actual download and installation of the full version of Microsoft Office on your local PC (and each license allow you to install it on up to 5 of your devices).
Microsoft Office 2013 Outlook gets the ribbon bar like the other Offcie applications. Strong integration to Microsofts cloud storage, SharePoint and SkyDrive.
