I have a peculiar problem I just can't seem to figure out. We are running exchange 2013 CU2. We are running multi-tenant, so we implemented Address Book Policies. The ABP seems to be working fine until we access the Address Book. For example, when in Outlook and a user is creating a new email they click on the "TO' button to bring up the Address List Dialog, and the list is blank. You can type something in the search box and click Go and it will surely find the user(s) no problem. But it is not displaying the entire list of names.
Did I forget something? All the users in the OU for that ABP have the Custom Attribute 1 set. I even added the Company name in the user properties. They have their own accepted domain and email SMTP address set. Everything seems to be set except for them not showing up in the AB. What am I missing?
