  We find exact, simple solutions to the Proca version of Maxwell's equations
with magnetic sources. Several properties of these solutions differ from the
usual case of magnetic charge with a massless photon: (i) the string
singularities of the usual 3-vector potentials become real singularities in the
magnetic fields; (ii) the different 3-vector potentials become gauge
inequivalent and physically distinct solutions; (iii) the magnetic field
depends on $r$ and $\theta$ and thus is no longer rotationally symmetric; (iv)
a combined system of electric and magnetic charge carries a field angular
momentum even when the electric and magnetic charges are located at the same
place i.e. for dyons); (v) for these dyons one recovers the standard Dirac
condition despite the photon being massive. We discuss the reason for this. We
conclude by proposing that the string singularity in the magnetic field of an
{\it isolated} magnetic charge suggests a confinement mechanism for magnetic
charge, similar to the flux tube confinement of quarks in QCD.
