What does “caching mode” mean and how does it affect my UMail Outlook mailbox?
UMail Outlook users enjoy a better online and offline messaging experience with the Caching setting because a copy of the user’s mailbox is stored on their local computer. It is the default setting for UMail users connecting with Outlook 2003. To learn more about Caching for Outlook, please see Microsoft’s Setting Up Outlook 2003 Cached Exchange Mode Accounts webpage.
