We present the results of muon-spin relaxation (\ensuremathμ+SR) measurements on the hexagonal manganite HoMnO3. Features in the temperature-dependent relaxation rate \ensuremathλ correlate with the magnetic transitions at 76, 38, and 34 K. The highest temperature transition, associated with the ordering of Mn3+ moments has the largest effect on \ensuremathλ. The application of a static electric field of E=5\ifmmode×\else\texttimes\fi106 Vm^\ensuremath-1 below T=50 K causes a small reduction in \ensuremathλ which is suggestive of coupling between ferroelectric and magnetic domain walls in the ordered state of the material.
