Is it possible for a document role to have the ability to Change Owner, but not have the ability to edit Sharing Settings for any other role in Vault?
It is not possible to be able to change the owner of a document without being granted permissions to Edit Sharing Settings for other roles. Granting a user either the Change Owner or Change Coordinator permissions grants the user permissions to the Edit Sharing Settings.
