... Any ideas how to mill out an open edge area? ...
As ChrisB suggested, and MLampert encourages, use the Extensions feature of the regular Pocket operation to extend edges, expanding access to such regions. See the last image.
: A second option is to select both the upper open edge face and the inner lower and clear them together at the upper face depth, then do a second clearing op with only the inner lower selected. See second and first image.
