In addition to the email and calendar services available to Cornell, Office 365 includes additional productivity and collaboration services. These include:

SharePoint Online
Group collaboration and app space for everything from file sharing to workflows.

OneDrive for Business
Personal, private file storage that can easily be shared to others when needed.

Office Online
Versions of Word, Excel, PowerPoint, and OneNote on the web that provide the most-needed features of Office for online editing.

Yammer
An enterprise social network that supports conversation with groups or all of Cornell. People outside the university can be invited to join groups.

Delve
An information surfacing feature that analyzes what's been shared with an individual in Office 365, including SharePoint Online, and what the person is working on, and displays information that seems most important for that person to know.
