The Kashiwara-Vergne conjecture states that the Campbell-Hausdorff series of a Lie algebra can be written using a certain couple of functions. In this paper we consider universal solutions which apply to every real finite-dimensional Lie algebra. We prove that a universal solution of the Kashiwara-Vergne conjecture verifying that a natural symmetry condition is unique up to order one. In the Appendix by the second author, this result is used to show that the solutions of the Kashiwara-Vergne conjecture for a quadratic Lie algebra which exist in literature are not universal.
