Closed Unassigned: Cannot Access ActiveSync Container from Root Container [16399]

I have used MFCMAPI with success in the past for deleting EAS accounts. I have come across an issue today where the EAS object was deleted from the container in ADUC, I would like to remove the partnership and have done so in the past using MFCMAPI.

My issue is that now I cannot access the ActiveSync Container like I have been previously. I have tried mulitple computers, with multiple accounts all using ActiveSync

Any suggestions?
