  • Meanwhile, users of Outlook 2003 working with higher versions of Exchange or vice versa are suggested to make upgrades to overcome compatibility and consistency issue. The data becomes more highly vulnerable to getting damaged with virus and other damaging issues when Microsoft stops offering updates. To fix such issues and recover data from corrupted OST file an appropriate OST converter application is required.

  • HI,

    I hope, you have solved your problem but if you are still looking for the solution then there is a way to repair your OST file manually. you need to open your Scanost.exe file, it is an MS Outlook built-in tool aka Inbox Repair Tool. It will diagnose and repair the errors in files.

    So just follow the steps.

    1. Double click on the scanost.exe
    2. Click on Browse and select the corrupted PST file
    3. Click the Start button.
    4. Now, check the make backup of scanned file before repairing 
    5. And now, Click on Repair
    6. Finally, Click on Ok button.

    If this doesn't work out them you download the OST File Recovery

  • It is only viewer tools for ost therefore you can view only data of OST files. It does not work when your Exchange Server goes to down for restore emails from OST files. You can try another tools like OST Recovery Software that supports to easily restore or open your OST file on offline mode.

    Thanks & Regards
