  • Hello Dennis,

    Convert an Offline File (.ost) to a Personal File (.pst)

    Utility from microsoft to convert ost file to pst file

    Note, the current forum is for developers. I'd suggest asking non-programming questions on the Outlook IT Pro Discussions forum instead.

    P.S. You can find a lot of commercial tools for that. Don't want to advertise any.

  • You need to make some actions:

    1. Close your Outlook email client if it is currently open.

    2. Click the "Start" menu and select "Run."

    3. Type without the quotes "drive:\Program Files\Common Files\System\Mapi\LocaleID scanost.exe" and press "Enter." Replace "drive" with the drive letter that holds your Outlook email client. It is typically your "C:\" drive. Replace "LocaleID" with the locale identifier for your Office installation. The LocaleID for English (United States) is "1033."

    4. Choose the option that says "Scan All Folders."

    5. Place a check mark next to "Repair Errors."

    6. Click the "Begin Scan" button. The scanning process may take several minutes to complete.

    7. Launch Outlook once the scanning is complete. Your .OST files should be recovered.

    Try Using OST to PST Converter Kit and get your .ost file converted into .pst file on address:-

    How To Convert an OST File To PST Freely?

    1. Make certain that you disconnect from the network and restart the Microsoft Outlook. After restarting, sign on the machine on which you want to create the OST file.
    2. The next step is to select ‘File’ and click on ‘Open and Export’ and then click on the option ‘Export or Import’ to run the Export and Import wizard smoothly.
    3. Click on Export to a file option and then select the Outlook data file from the list of the
      available formats and then select the email address you want to export data from and click on the ‘Next’ option.
    4. Save the name for your backup file and click on OK.
    5. The next step is to select the ‘Allow Duplicates to Be Created’ option and click finish.
    6. Put an optional password to safeguard the data and export it.
    7. Sign on to a separate account and open Microsoft Outlook and select the file and click ‘Open and Export’ option to run the ‘Import and Export’, wizard.
    8. Select the option ‘Import from another file’ and click browse and then move to the network which contains the PST file you created.
