Microsoft Office Web Apps are a part of most Office 365 plans. Office Web Apps make it easier for you to work in the cloud because they open Word, Excel, PowerPoint, and OneNote documents in your web browser.
Documents that are stored in your SkyDrive and your team sites, attachments in Outlook Web App, meeting notes in Lync Web App: you have access to these whenever you have an Internet connection, from almost any device. And sharing documents with others is as simple as sending a link.
To get started, sign in to Office and save your document online. Your school or business plan gives you a SkyDrive Pro location for storing your documents. You can also store team documents in a library on your organization’s team site. If you have Office 365 Home Premium, you have a personal SkyDrive location at SkyDrive.com.
Just click a document to open it in the browser. Attachments in Outlook Web App and Outlook.com open in the browser, too. So do meeting notes in Lync Web App.
