Learn about OneDrive for Business, a cloud-based system for creating, storing, sharing, and organizing your work documents.

Microsoft OneDrive is Microsoft’s document creation, collaboration and storage platform. Microsoft OneDrive allows collaborators to:​

  • Create and new documents including Documents, Spreadsheets, and Slides.​
  • Share the documents and edit them with collaborators.​
  • Upload and store any existing files or documents for easy access and sharing


  • It's free: UC San Diego has a licensing agreement with Microsoft.
  • It's universal: All UC San Diego students, faculty, and staff have access to the UC San Diego Microsoft OneDrive environment.
  • It's secure: Storage conforms to HIPAA (Health Insurance Portability and Accountability Act) requirements.
  • It's compliant. The negotiated licensing terms dictate that data be stored on U.S. soil which fulfills export control requirements.

Best for

  • Storing files (each user gets 5TB of space)
  • Syncing files with your local computer
