With web-based Microsoft Apps you really can access your office from anywhere. Store files on your OneDrive in the Cloud, and simply log in via a web browser.
You can choose when to share your documents, specifying who can view only and who can edit. Your documents are private until you share them.
If you work on Microsoft Desktop apps on your PC or Mac, your files will still contain the same formatting and layout when you open them using Microsoft Online.
