re:

Maybe try removing the Microsoft account and then adding it back?

Thanks for the reply. I had previously removed and then reinstalled. And discovered it was user interface issue in that I had not selected the correct calendar. Marshmallow update worked as it should. However, I'm still trying to figure out how to make the exchange calendar the default. Still learning....thanks again.
