Hi Kristina, 

Welcome to the Box Community!

I recommend that you reach out to your Box Admin, they have the ability to "transfer folder ownership" through Admin console.

You can provide this article to the Admin for reference: https://support.box.com/hc/en-us/articles/360044197333-Using-the-Content-Manager 

Thank you for posting!

Best,
Ann

Hi Ann, I don't know who my Box Admin is. How can I find that person?

Thank you!

Kristina
