Visit OneDrive for Business web page
OneDrive for Business, available as part of the Nexus365 suite of tools, is Microsoft's file-hosting service. Each user is allocated 100GB of secure personal storage; files can be shared with other users (including both other University members and external guests) and synchronised between different devices.
Note that the OneDrive for Business service is distinct from the version of OneDrive that you may have access to via a personal Microsoft account. While OneDrive for Business is a sufficiently secure service for use with all categories of University data, including confidential information, personal accounts are not covered by the specific terms and conditions that the University has negotiated with Microsoft, and thus are generally not recommended for storing research data.
