I had the same problem during HMC 3.5 -> HMC 4.0 migration. As I found, the reason was the fact that
Exchange 2007 setup didn’t grant read access to existing OAB/AL for domain group ‘Exchange Servers’. So, make sure, that OAB server itself has enough rights to read both organization's AL and
OAB objects in AD.
I would recommend you to read Dave Goldman's BLOG about this:
