• If you use Web-based distribution, the Client Access server replicates the files. If you use public folder distribution, the OAB generation process places the files directly in one of the public folders, and then the Exchange store replication copies the data to other public folder distribution points.
  
  
• Client computers that are running Outlook periodically check for and download OAB updates. For information about how to modify when OAB generation occurs, see Configure Offline Address Book Properties.
  
  
• If your organization contains Exchange Server 2003 servers, you can generate the OAB from an Exchange 2003 server provided that public folder distribution is enabled. However, if you generate the OAB from an Exchange 2003 server, you will lose the following functionality:
  
  
  • Japanese phonetic display name
    
    
  • Japanese phonetic surname
    
    
  • Japanese phonetic given name
    
    
  • Japanese phonetic company name
    
    
  • Japanese phonetic department name
    
    
  • PR_DISPLAY_TYPE_EX, which is used by Office Outlook 2007 and later to render the correct icon for objects that are replicated across the forest.
    
    

• Use the EMC to move OAB generation to another server
  
  
• Use the Shell to move OAB generation to another server
