OST file created when we connected MS Outlook client to MS Exchange Server. OST files allow users to work in offline mode, that is, when there is less or no network connectivity available. And when network connection gets connected, OST files get synchronized with the user mailbox on MS Exchange Server. To transform OST file out of MS Exchange Server environment, manual conversion from OST to PST performed such that all the mail items including Inbox, Outbox, Contacts, and Calendar Entries etc. could be accessed without having connection to MS Exchange Server.
