Thanks for the reply qPs1. I tried the steps mentioned in the above thread, minus the DM sync procedures. As JSanders suggested, I set my default calendar to the calendar most of my appointments are related to. All I did then was delete the service books associated with my email accounts (service books ending in CICAL). Once the service books were deleted, my appointments and calendar entries appeared on the home screen.
I decided to resend my service books and at that point the entries disappeared from my home screen. It doesn't seem to matter which calendar is select in "default services", none allow my appointments to properly display on the home screen. Only solution seems to be deleting the service books...
Any other suggestions? Once the service books are deleted, there is no default calendar option in the default services screen (which is to be expected).
