Have the address book show all address lists from Exchange
Currently the Address Book in Outlook for the Mac is not able to show all Address Lists on the Exchange server or in Exchange Online.
If you create a custom address list in Exchange it does not show up in Outlook for Mac.
In Outlook for Windows or even in Outlook on the Web you can see custom Address Lists or even more default Address List on the Exchange Server.
Using Outlook under different operating systems is cumbersome as there is no feature parity among the different clients.
