How to fix common PST File corruption errors

Though Outlook is one of the robust and largely used email clients across the globe but Outlook data files or Personal Storage Table (PST file) files to store emails, contacts, tasks, notes, etc are really very fragile. The Outlook PST files are prone to get corrupt due to reasons like virus infection, power failure, abrupt Outlook shutdown, etc. Most of the times a corrupt PST file renders errors thus we become unable to access any mailbox item stored on this PST file. Though Outlook provides inbuilt tool named Inbox Repair Tool or Scanpst.exe to troubleshoot issues related to PST corruption but at times this tool too fails to do the needful. At such situation, a user has to refer some third-party PST repair software.
