I have a new install of Unity 7.02 UM with an Exchange 2003 integration. The integration has gone smooth to a point and I can import users directly from Exchange with no problem. My problem is that once the subscriber has been imported into Unity, if I then edit the subscribers extension number and click save, the subscriber account is changed to an Internet Subscriber account with no mail-store within Unity. I have re-run permissions wizard and everything shows clean, I also have confirmed that the Unity installation account and directory services accounts have been granted Exchange Administrator rights. This seems like a permissions issue but the logs are clean. Once I import a subscriber I can edit any other attribute without any issues. It is only when I edit the subscribers extension that the subscriber is changed to an internet subscriber. Any help in pointing me in the right direction for a posible fix would be greatly appreciated.
