Hide from Address List without Schema Extension
Admin User needs to do schema extension for their AD environment to modify msExchHideFromAddressLists attribute.
Without the schema extension, they are not able to set to hide user from address list.
This is inconvenient situation for users while they would not extend the schema.
Admin User prefers to be able to set user to hide from address list without schema extension.
