transferring owner status to another co-owner

Hi Lucy,

Welcome to Box Community and glad to assist!

As an owner, you can transfer folder ownership to a collaborator at any time. Simply follow the instructions: 

1. Locate the appropriate folder. 
2. Click the Collaboration Icon to the right of the folder name.
3. Alternatively, you can open More Options > More Actions and select Manage Collaborators.
4. Find the collaborator whose access level you would like to modify. You can search by name using the Filter Collaborators search box in the upper right.
5. Under the Permissions column, click the user's access level to modify it. Select the appropriate access level from the dropdown that appears. Note: Collaborators in single files can only be granted the Editor and Viewer access levels.

Hope it works!
