I am developing a workflow solution using Exchange 2000. Problem I am facing is that how to maintain the hierarchical structure on posted items in a public folder. Once I give Read Item Permission in the properties of the public folder, then all items are visible to that user, but as per the requirement, User should be able to see only Items he has created or items arrived to him for approval (if he is manager to some other user). Please help me in this regard ASAP. Thanks, Gaurav
