  Using Fedosov's approach we give a geometric construction of a formal
symplectic groupoid over any Poisson manifold endowed with a torsion-free
Poisson contravariant connection. In the case of Kaehler-Poisson manifolds this
construction provides, in particular, the formal symplectic groupoids with
separation of variables. We show that the dual of a semisimple Lie algebra does
not admit torsion-free Poisson contravariant connections.
