Cached Exchange Mode give users a seamless online and offline Outlook experience. It also insulates users from network latency and connectivity issues while they are using Outlook. By caching the user's mailbox and the OAB locally with Cached Exchange Mode, Outlook no longer depends on continuous network connectivity for access to user information. While connected, Outlook continuously updates users mailboxes so that the mailboxes are kept up-to-date.
