The Office Hub on your phone is the place to go to work on your Microsoft Office documents. Go there to find documents, open them, and make last-minute changes to them, or even start new documents. In the App list, tap Office to get started. In there, you'll see a couple of different ways to find and open your documents.
Recent – Quickly find and open documents you've recently used. Or if you want, start a new document from here.
Places – Get to Office documents that are on your phone or saved someplace else, such as on Microsoft OneDrive, on a Microsoft SharePoint 2010 site, or on a SharePoint Online site (which is available with Microsoft Office 365). And if you've opened documents from email, you can tap Email to get to them.
