Office Online (Word, Excel, PowerPoint, OneNote)
You can use Office Online applications (Word, Excel, PowerPoint, OneNote) on almost any web browser. All you need is an internet connection.
The Office Online service enables you to use Word, Excel, PowerPoint and OneNote through a web browser. This is possible even though these Office applications would not have been downloaded on your device.
Never store confidential or sensitive data on OneDrive: identity or banking information and trade secrets are to be handled elsewhere.
You can access OneDrive for Business using the following link http://o365.luc.fi
