In the Cached Exchange Mode, a copy of your mailbox is saved on your computer. The copy offers prompt access to your data and is often updated with the server that runs Microsoft Exchange. Cached mode is the default when you add an exchange or Microsoft 365 account. You cannot use a Cached Exchange Mode with a POP or IMAP account.

If you notice that the Cache Exchange Mode is greyed out, this means that you only have a POP3 or IMAP account in Outlook. The option is also greyed out if you are using Windows Server with Terminal Services installed.
What happens when you disable cached Exchange Mode?
If Cached Exchange Mode is disabled, the program will be slower to process changes in the Global Address list or will be unable to find certain emails when you search for them.
What is the difference between cached Exchange mode and online mode?
There are two methods to connect to an Outlook Exchange account: Online Mode and Cached Exchange Mode. Online Mode maintains a direct connection to an Exchange server, while Cached Exchange Mode creates a local copy of the mailbox data stored on the Exchange server in an Offline data file.
Should I use Cached Exchange Mode?
It is recommended to always use Cached Exchange Mode with a Microsoft 365 account. The Online Mode works by using information directly from the server, and it requires a connection.

You cannot use Cached Exchange Mode with a POP or IMAP account.
