Currently, if you share a folder with someone, they get an email that lists up to the first ten items in that folder. If the file names have Patient Health Information in them (e.g. if they contain the name of the patient) then this could result in PHI inadvertently being sent via email, in violation of HIPAA security policies. If we could turn this off in our Box instance, so that invited collaborators get an email but not a listing of contents, then there would be no unintended sending of PHI via email.
