Yes, I opened ADSIEdit, went to
CN=Default Global Address List,CN=All Global Address Lists,CN=Address Lists Container,CN=HMC 40 Green Field Test,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ad,DC=dom ain,DC=biz
And add Read and Open List permissions, voila it seems to work now
I'll report when I finish activating a device/user.
