A.T. Robertson Commentary Mark 16:13

"And they went away and told it unto the rest: neither believed they them." — Mark 16:13 (ASV)

Neither believed they them (ουδε εκεινοις επιστευσαν). The men fared no better than the women. But Luke's report of the two on the way to Emmaus is to the effect that they met a hearty welcome by them in Jerusalem (Luke 24:33–35). This shows the independence of the two narratives on this point. There was probably an element who still discredited all the resurrection stories as was true on the mountain in Galilee later when "some doubted" (Matthew 28:17).
