Microsoft Office Online programs are a part of most Office 365 plans. Office Online programs make it easier for you to work in the cloud because they open Word, Excel, PowerPoint, and OneNote in your web browser.
You can view your documents whenever you have an Internet connection, from almost any device:
Documents stored in your team sites
Attachments in Outlook Web App
Meeting notes in Lync Web App
And sharing documents with others in your organization is as simple as sending a link.
When you use the three-dot Open Menu in a SharePoint library, Office Online shows a preview of the document, and provides another Open Menu with commands for viewing and editing the document in your browser.
To get started, upload files or create new files and save in your organization’s libraries.
