Hi Dan,
Welcome to Box Community and glad to assist!
Only the folder owner can transfer the folder ownership and there's no alternate workaround on this one.
Meanwhile, to take ownership of a folder, it would only take a single user.
To know more about transferring folder ownership, please visit this article.

Thank you for your reply Rona.
So just to confirm, the recommendation would be to re-create the folder in my box account, re-upload the files and then share with all the same users, as the original owner does not have access to their email so cannot transfer ownership?
Hi Dan,
Good day!
At this time, you may download and re-upload the files/folders on box.com so you and your collaborators could continue to work on those contents.
