What does the OST file extension denote?

Explanation:
The OST extension denotes a local cache used by Microsoft Outlook to provide offline access to a mailbox stored on an Exchange server. The standard expansion is Offline Storage Table. Outlook creates an OST file when you use an Exchange (or Office 365) account in Cached Exchange Mode, storing emails, calendar items, contacts, and other mailbox data on your computer so you can work offline. When you reconnect to the network, changes sync back to the server. This is different from a PST file, which is a local data store for archiving or personal storage without automatic server synchronization. Some descriptions may informally describe it as “Offline Outlook Storage,” but the canonical term is Offline Storage Table.
