Office Online is a light, online version of Microsoft's Office 2016 suite including Word, PowerPoint, Excel, and Outlook.
While it may not have all the features of the local Office 2016 suite, it does provide the ability to access the Office 2016 through any browser, on any computer, so long as you have internet access. It also provides collaboration opportunities, as multiple users can work on the same document simultaneously through Office Online.
To access Office Online, visit to office365.stfx.ca, log in with your StFX email address and password, and then click on any of the square tiles to access that Online app.
