What it serves
Microsoft's article on required URLs and ports for OneDrive lists these hosts, with many others, for the consumer version of OneDrive.
Microsoft points to its Microsoft 365 URL list for OneDrive in work and school accounts. That list is different.

What breaks if you block it
- The OneDrive app can't upload or download files.
- onedrive.live.com doesn't load in the browser.
With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s Protection lists.
Notes
Microsoft warns that filtering internet traffic needs advanced networking knowledge and isn't suitable for all customers.
