creating todo's for another salesperson

Hi, In navision it is possible to create a todo which is then synchronized with outlook. Now lets say there is a salesperson “A” and a salesperson “B”.Now the person B creates a todo for person “A” in navision. Now i want to be able to change the field Owner on the outlook task with the name of person “B”. I already tried to add the following code in the CreateTaskItem() function but it didn’t change the owner field in the outlook TaskItem.Owner := Todo.CreatorTodo; CreatorTodo is a code(10) field with the code of person B. Is there another solution ? thx, Wendy
