Why isn't my exchange calendar syncing from my Android table (LG v500) to hosted Exchange server?

Exchange calendar not syncing FROM android table (LG v500) to hosted Exchange server

Spent an hour with the tech at the hosted Exchange provider. Removed Exchange from tablet, reconfigured, restarted tablet 3 times. Same problem. Calendar items created on tablet do not sync to server and thus not to desktop/laptop.
