What is LionBox? A 3rd party application? Is the folder shared or are there any collaborators on the folder? You may need to refer to their docs to confirm how sharing works.

Is there a help phone number.  Lionbox is a shared sts application for Publicis or Lion Resources.  Yes there are other colloborators.   I was given this email as the help email when there are issues with it?

Since it's a 3rd party application, it will be supported by Lionbox. I found this resource from them regarding support-> http://www.lionbox.publicisgroupe.net/#support .It looks like the application was built on the Box API which is why it looks so similar, so I understand why their would be some confusion. I would imaging sharing and collaboration would be the same, but its hard to say without more info. Also I don't work for Box I'm just a user as well.
