I could not remove the owner of a group, although I am admin/company package. Only when the owner demoted himself (after promoting somebody else to group owner) I could get him to leave the group. This could be a problem when facing bad leavers ... (Even removing/disabling the owner's boxcryptor account in the web panel - which I am entitled to do as admin - did not help...)
