Hi All, I am looking everywhere for a permission I must be missing. I need to be able to allow a user to administer user account attributes in AD (which is done through delegation) but I also need that person to be able to modify the Exchange Custom Attributes as well. Does anyone know how to assign this permission? The user can see the values and has the tools installed, can open the attribute and only when he tries to save the changed value does he get 'access denied'.... TIA
