You can access the public folders that are displayed in the Favorites folder under Public Folders when you don't have a connection to your mail server or are working offline.

Note

  • This feature requires a Microsoft Exchange Server account configured to use Cached Exchange Mode.
  • Large  outlook data files can cause Outlook to run slowly. If you have public folders large than 10GB, we recommend you not configure caching to avoid performance issues with Outlook.
