ok, here goes. I'll create an appt. in galaxy calendar, using my main exchange acct, but it does not sync to my desktop outlook. also, i'll create an appt. on desktop, and won't sync to galaxy calendar. However, I use 9folders for my mail, and it's calendar is syncing fine. with the galaxy note 7, it is rather confusing to find exactly where the exchange accounts are located, how to delete, and then re-enter. in my settings, under accounts, i see the 9folders, but dont actually see any exchange accounts.
device: galaxy note 7, 6.0.1
