FILE_ATTRIBUTE_OFFLINE is used for files on Windows SMB shares. Microsoft writes about it "The data of a file is not available immediately. This attribute indicates that the file data is physically moved to offline storage. This attribute is used by Remote Storage, which is the hierarchical storage management software. Applications should not arbitrarily change this attribute.". It seems to be used for data which isn't immediately available on the server, e.g. on a tape drive.

I didn't see it used for OneDrive.
