OST (Offline Storage Table) files are Outlook Data Files, which store mailbox data of Microsoft Outlook. Their basic functionality is to provide access to Outlook emails and other mailbox items during unavailability of internet. In simple words, OST files allow you to send/receive emails and other information during offline mode. You can still work with MS Outlook if it’s not connected to the Exchange Server. That’s why OST files are also called Offline folder files.
OST files get corrupted due to a lot of reasons. Virus intrusions, Exchange Server failure, hard disk failures, abrupt Outlook termination, synchronization issue between MS Outlook and Exchange Server, poor internet connectivity, sudden power failure or system shutdown etc. are some of the major reasons that can cause OST corruption.
