Exchange Sync Issues with Android 4.4.3 KitKat

Ok, so I own a launch 16 GB Moto G. Everything worked fine under 4.3 Jelly Bean. After upgrading to 4.4.2 KitKat, however, the Exchange issues began popping up. Email is often slower to load in, and my calendar absolutely refuses to sync. Every time I try, I get the "Unfortunately, Exchange Services has stopped" error message. Upgrading to 4.4.3 yesterday didn't help at all. I already tried deleting my account off the phone and clearing the cache related to the email app. Does anybody have any ideas?
