Offline Storage Table (OST) is a file in Microsoft Outlook that allows users to work offline and have changes reflected when they reconnect with the Exchange Server. In the event of OST corruption, the GSTECH OST to PST Export Program is an effective tool for recovering emails and converting the OST file to PST, regardless of the file size. This conversion tool is useful for recovering lost or corrupted OST files due to hardware or software issues.
