The full form of OST is Offline Storage Table.
An OST file, or offline storage table (.ost) file, is an offline Outlook Data File used by Microsoft Exchange Server that enables users to work with their messages and mail data even when access to the mail server isn’t available. OST files are used in two scenarios: with Microsoft Exchange Server’s Cached Exchange Mode and with the Outlook Connector for Windows Live Hotmail when accessing Hotmail mail.
