Setting up OWA on an iphoneiphone 4

Hello EE. I am having a hell of a time trying to get one iphone4 user to to access OWA on Exchange 2010. I was able to successfyully set up 3 others with no problem. It keeps giving me "Exchange Account Unable to verify account information."
The only difference between her phone and the others is the OS is running 4.2.1 and the others are running 4.1. Inheritable permissions is checked on her AD profile. I was getting event id 1503:

 Exchange ActiveSync doesn't have sufficient permissions to create the "CN=User,OU=XXXXX_XXXXX Administrators,DC=MHACS,DC=local" container under Active Directory user "Active Directory operation failed on MHAS.MHACS.local. This error is not retriable. Additional information: Access is denied.
Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
".
Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type "msExchangeActiveSyncDevices" and doesn't have any deny permissions that block such operations.

Details:%3

After checking allow inheritable rights in security tab I stopped getting that error but I still can not sync the phone. I tried with and without SSL. I do have a valid SSL ceert from GoDaddy. The other 3 phones gave no problems.. I have Exchange 2010 running on Windows 2008 R2 standard with a DC running Win 2008 R2 Enterprise. My luck she happens to be an Executive Administrator and is a domain admin as well. Any help would be appreciated.
