I appreciate your help on this. I just re-opened my outlook and it was gone... I have no clue what I did since I was playing around with it for a few hours early today and then hadn't done anything else. There must have been a delay in something I had tried and it didn't take effect right away. I wish I knew what I did to fix it to help someone else out. Thanks again for attempting to help me fix this! Have a great weekend.

Only after Outlook performed a successful autodiscover on your mailbox you got to see the effect of your configuration changes.
  
  P.S. Interesting post explaining why the backlinks (msExchDelegateListBL) in AD are read only:
