Answer 1

Here are the questions I need you to answer:
1) If you plan on integrating with Exchange 2007, my assumption is that you are planning on a Unified Messaging deployment and you will be integrating with your CORPORATE (i.e., existing) Active Directory and Exchange 2007 environment.  Is that correct?  If not, and you are installing a standalone Unity messaging environment then my advice is to use Exchange 2003 as this will provide better ease of use in a standalone environment for you (I'll get to this point in more detail as I answer your questions).
2) Do you need to configure OAB for Outlook 2003 and Earlier Clients even if all of your users have Outlook 2007?  Yes.  I believe the actual setting in E2K7 may not read exactly as it is written here but the premise is the same which is why the statement "regardless of which versions of Outlook you are using" is included in the installation notes.
3) What is the difference between Unity with Exchange 2003 vs. Exchange 2007?
- With Exchange 2007, Unity cannot create mailboxes directly in Exchange due to permission restrictions.  All users and mailboxes must exist before you create a Unity subscriber.  Going back to #1, if you are doing a standalone environment then Exchange 2003 integration is easier from an adminstration perspective.  Unity can create AD users and mailboxes for you with Exchange 2003 but not with Exchange 2007.
- Expanding on your second question, even with Exchange 2007 the Exchange 2003 System Manager is installed on the Cisco Unity server because it includes the Microsoft messaging API (MAPI) that Unity uses to communicate with Exchange for addressing, sending, and retrieving messages. When using Exchange 2007 as the partner Exchange server for Cisco Unity, offline address books for “Outlook 2003 and earlier clients” should be configured regardless of which version of Outlook is being used or Cisco Unity will not function properly.
- If you are running a mixed environment of 2003 and 2007 Exchange servers, the Unity partner server must be an Exchange 2007 server.
- When you install Unity with Exchange 2007, you must run a script on the Exchange 2007 server during the installation.  This is a Power Shell script that creates the primary system accounts (3 of them) that Unity needs to operate because again, it cannot create mailboxes in an integration with Exchange 2007.
That's all the primary points.
