Address Book not showing exchange contacts

Our company uses Office 365 with our macs running Lion. Email and calendar work as expected, however there doesn't seem to be any easy way to view our GAL or distribution groups, or any contacts from the exchange account.

When you go into address book you can see the global address list. When you click on it, it does not show anything. However, if you search for a contact or distribution list it shows up fine. I've heard there is a setting you can change to get this to work but i've not had any luck finding it through google or apple support. Anyone have any ideas on this ? Thanks in advance.
