How to Enable Cached Exchange Mode? | Complete Guide

Enabling Cached Exchange Mode creates a copy of the mailbox data items stored on the Exchange server in an OST file format on your local computer. It reduces the number of requests made to the server and thereby improves the speed to access Outlook items such as emails, contacts, etc. 

Due to the Cached Exchange Mode, Outlook is nowhere dependent on the constant internet connectivity to access the user’s information. Thus, enabling the Cached Exchange mode helps users to work on Outlook without network connectivity. 

Later, the local and server data is synchronized by Outlook and the Exchange Server after the connectivity is back. This helps improve the usage of Outlook when there is a slow or no internet connection. The latest Outlook such as Outlook 2019 is available for Work offline mode.
