OneDrive for Business

Last updated: April 15, 2024

OneDrive for Business is a UW Office 365 cloud service that connects you to all your files. It lets you store and protect your files, share them with others, and get to them from anywhere on all your devices.

Please note: While OneDrive for Business integrates with other UW Office 365 services, the service is designed as an individual file collaboration solution. For those in need of a platform designed for collaborating on files with a group of people, please see the UW 365 Office Collaboration Services page for more options.

Service restrictions and limitations

External Sharing Disabled

External Sharing is disabled on UW OneDrive for Business accounts, which means you will not be able to share files outside of the UW, i.e. with individuals with a non-UW email address. This restriction was implemented after careful consideration of the risks and challenges associated with monitoring the potential sharing of sensitive information (e.g. HIPAA-regulated data) outside of the UW using OneDrive for Business.

If you’d like to utilize a similar platform and share with external users, you can request a Microsoft Team or SharePoint Online site collection with external sharing enabled.
