Nokia :: E72 Where Are Exchange / Microsoft Outlook Contacts?

I successfully set up the Exchange client on my E72 and can receive and send mail but I cannot find my contacts that are on our server at work via Microsoft Outlook. Phone support at Nokia was not helpful - very frustrating. My personal contacts synch with the E72 fine from my Mac using Apple Address Book and Sync. Am I correct in thinking that I can maintain both my Microsoft Outlook work contacts and Apple Address Book contacts at the same time? I thought the E72 was capable of this.
