Office Online (via Office 365)

Office Online is a free version of Office that you can use in your web browser or mobile device.

Members of the University of Guelph will have access to lightweight online versions of Microsoft Word, Excel, PowerPoint and OneNote.

Office Online offers users the ability to lightly view and edit their documents, while the Microsoft Office desktop applications offers users the full features and functions of Office.
