Group Policy denies storage of Bitlocker recovery information

Hi,

I have started to implement BitLocker to laptops in my organisation starting with a few test machines.

I configured a GPO and applied it to my 'test laptops' OU configured with the following settings:

Computer Configuration > Policies > Administrative Templates > Windows Components > BitLocker Drive Encryption
 - Turn on BitLocker Backups to Active Directory Domain Services (also ticked 'Require BitLocker backup to ADDS')

Computer Configuration > Policies > Administrative Templates > System > Trusted Platform Module Services
 - Turn on TPM Backup to Active Directory Domain Services (also ticked 'Require TPM backup to ADDS')

I then ran a gpupdate /force on my test machine, rebooted for good measure and then tried manually backing up the BitLocker/TPM data to ADDS using the following commands

manage-bde -protectors -get c:

Volume C: []

All Key Protectors

  TPM:

   ID: {C15C7DBE-956D-4F48-9CB1-D4A024651530}

  Numerical Password:

   ID: {57FA6ECB-832D-4068-B4E8-E6A4D0250796}

   Password:

    XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX

manage-bde -protectors -adbackup c: -id {57FA6ECB-832D-4068-B4E8-E6A4D0250796}

ERROR: Group policy does not permit the storage of recovery information to Active Directory. The operation was not attempted.

I removed this GPO link, did a gpupdate /force and another reboot to remove the settings from the GPO and receive the same problem. I have checked all other GPOs and none contain anything tat should restrict the updating of information to ADDS.
