OneDrive can be accessed through the web by signing into your Email/Office 365 account. You can also set it up on your work or personal computer to sync files automatically between your computer and OneDrive.
You should now see a new folder called OneDrive for Business in File Explorer.
Any files or folders saved here will automatically be synced to your OneDrive on the web.
If you already have many files saved to your OneDrive on the web it may take several minutes for the initial sync to complete.
IMPORTANT REMINDER: Files synced with OneDrive will be synced across every device you've setup with OneDrive and signed in with the same account. It's important to keep that in mind if friends or family might have access to your OneDrive files while using your personal computer.
