A Microsoft 365 Document Storage and Collaboration Solution

OneDrive is a document and file storage hub in Cornell's Microsoft 365. It's easy to upload, download, and share files. You can also create, view, and edit documents online using the integrated Office Online applications, Word, Excel, and PowerPoint. For those times you need the complete set of Office features, you can open your files in the full version of the applications and save them to your hard drive or back to the cloud.

Cornell OneDrive provides a place for Office for iPhone, iPad, and Android to store their files, where they will then be available to any computer or device through apps or a web browser. OneDrive for Business also can sync your files stored in the cloud with your Windows or Mac computer.

Because OneDrive is connected to your status at Cornell, everything stored in it will be deleted should you leave the university. For this reason, it's best to use it to store materials that are for your own personal business use, and store things that will be important for your unit or other groups at the university indefinitely in a Microsoft Teams team.
