Can a group have co-owner permission

Hi Aimee, 

Welcome to the Box Community!

Yes, Admins can certainly grant groups with 'Co-owner' permission. To do this:

• Go to Admin Console > click "Users and Groups" menu > Groups tab
• Find the specific group > Shared folders > Click "Edit" 
• Choose the access level that members of this group will have in the folders you have invited them into by clicking into the Permissions Dropdown. You can give the group different permissions in different folders. Once you are ready to continue, click Done.
