Vanderbilt students are eligible for a free of charge subscription to Microsoft Office 365 ProPlus through the Microsoft Student Advantage Program.
Subscriptions initially included 1TB of storage through OneDrive for Business. Microsoft recently announced it is dropping the storage limit. Office 365 subscribers now get unlimited OneDrive storage.
Student Advantage customers will see their storage upgrades during 2015.
