Motorola Droid X :: Calendar Events And Contacts Won't Sync Fully - Email Fine

I have a DroidX version 2.2.1 and I use Corporate email. When I type in a new Calendar event into the phone it sync's to Google fine but it does not sync to my Corp Calendar. The same happens for Contacts. Here's what I've found:

1) Phone to Google works
2) Phone to Corp does not work
3) Corp to Phone works
4) Corp to Google does not work

When I first setup the phone, I setup Corp email and Gmail and the sync worked well. Some time later I removed my Corp email account from the phone only to re-add it a couple weeks later. Since then, the sync does not work the way it once did. I have set the phone so that my Corp account is the default account. I receive email on the phone with no issues. I want my Corp Calendar/Contacts to match my phone no matter whether I enter them from the phone, Google or my Corp Desktop.
