Cached exchange mode意思

"Cached Exchange Mode" 是一種電子郵件同步方式，通常在Microsoft Outlook中使用，它允許用戶在脫機狀態下訪問他們的電子郵件、聯繫人和日曆條目。在這種模式下， a copy of your mailbox data is stored on your local computer, which allows you to access your email even if you are not connected to the internet or your Exchange server is unavailable.

When Cached Exchange Mode is enabled, Outlook downloads a copy of your mailbox to your computer's hard drive in a form of an offline Outlook Data File (.ost). This file is synchronized with the Exchange server whenever you are connected to the network. You can work with your email, calendar, and contacts as you normally would, and the changes are synced back to the server when you're online.

Cached Exchange Mode provides several benefits, including improved performance, especially in environments with slow network connections, as most of the work is done locally on your computer. It also allows for continued access to your email if you are disconnected from the server, and it can improve the overall Outlook experience by reducing the amount of time it takes to open or switch folders.

However, it's important to note that Cached Exchange Mode requires more disk space on your computer because it stores a copy of your mailbox data locally. Additionally, if you make changes to your Exchange mailbox using another device or application, those changes will not be visible in Outlook until the next synchronization.
