I have just had the same problem after an android upgrade on my sony xperia Z5. And luckily fixed it. I had to delete the account and then re-add it. I think I know why this worked as I have seen a similar problem before (with dropbox about 2 upgrades ago): with this new android version a new security feature was added and exchange couldn't automatically ...
I fixed this by installing Google Calendar. I already had Calendar installed, from gapps (needed with CyanogenMod). Now I have two Calendar apps installed, both called the same thing. Sync suddenly works, and the new calendar has a bit nicer UI.
