hi sebastian,
in onedrive for business, we can give the owner’s permissions for a folder to other users, and we will remain the owner of the onedrive for business library.
here are the steps to share a folder with the owner’s permissions:
- right click the folder, and then click share > shared with > advanced.
- click stop inheriting permissions, and then click grant permissions.
- input the user name and select full control as the permission level.
meanwhile, i’d like to explain that onedrive for business is mainly for personal use. for better collaboration with your team members, i would suggest you use a sharepoint team site library.
here is an article for your reference:
should i save my documents to onedrive for business or a team site?
