Cached Exchange Mode is one of the two modes to connect the Outlook application with an Exchange Server. The other one is Online Mode. The Cached mode has the job of keeping a local copy of the user’s Exchange mailbox stored on the hard drive in the form of an OST file. While the Cached mode is enabled in Outlook, the Outlook client will check the OST file for all the information and constantly update the mail and synchronize it to open the cached file.

A user can make changes in the mailbox, like accessing emails and saving drafts even when the Internet is down.
It is useful for high latency connections.
Searching files and information is quite easy in offline storage (OST) files.
In satellite and radio-frequency-based connections, the OST file works much better than the online files.

If the OST file that has been created after enabling the Exchange Mode becomes corrupt, then all its data will be lost before connecting with the Exchange Server. Also, if the OST file gets disassociated with the account, all information saved will be lost.
