Before discussing how to repair corrupted OST file, let’s understand what is OST file? Microsoft Outlook creates an OST file, an offline data file. It's used to keep a backup of Exchange Server mailbox data. OST files are local files that allow users to view their emails and other mailbox information when they don't access the Internet. For some causes, a user's Exchange server mailbox can become corrupted or even removed from the server. There's no need to fear, though, because the user's deleted files are frequently still stored on the local client system (MS Outlook) and may be recovered using free data recovery software.
