Force Outlook 2007 or Outlook 2003 to resolve proxy addresses and custom properties in Cached Exchange Mode
When you use Microsoft Office Outlook 2007 or Microsoft Office Outlook 2003 in Cached Exchange Mode, Outlook verifies and resolves the names of e-mail recipients with the Offline Address Book. The process of resolving e-mail addresses with similar fields, such as the DisplayName, is called Ambiguous Name Resolution (ANR).
