Letu be a harmonic function on a symmetric space which is the Poisson integral of a functionf inLp , 1 ≤p ≤ ∞. Thenu converges restrictedly and admissibly tof almost everywhere. This result is proved by obtaining an appropriate maximal theorem which takes into account the structure of the Poisson kernel.
