We'd really like to replace our Citrix ShareFile with OneDrive for Business. One issue we have is the ability for external users to see one another as members of a folder no matter what basic access level they have (view, edit). I've tested as an external users myself and can always see other members.
Is there a way to hide folder/file membership from external users? If we're sharing files to external parties, it is typically either inappropriate or unnecessary for them to be able to see who else has access to files. We don't need banks or lawyers to be able to see who else is involved in a project.
There are very few cases where it would actually be beneficial for external users to be able to see shared file membership.
