  • You cannot convert a OST file to a PST directly, There is security in place that ties the Exchange mailbox,OST file and MAPI profile together. That means that you need the be loged in with the original MAPI profile in order to open the OST file, if you can do that you can simply export or copy all data to a PST file.

  • PST file is a centralized database i.e. used to store all kind of items in MS Outlook. With reported error “outlook data file cannot be accessed”, situation seems alarm situation for MS Outlook PST file. After seeing any kind of error or corruption, user normally goes through ScanPST.exe but fails to retrieve expected result.

    In this case, you can use a tool from http://www.pst.repair

  • Hi,haydeen

    There are several methods to convert OST file to PST file.

    First, Microsoft does not provide an official tool to do the conversion. However, if you can access the contents of the OST file in your Outlook, then you can perform the conversion manually, as follows:

    1. Start Outlook. Make sure you can access all the contents in the OST file to be converted.
    2. Create a new PST file.
    3. Go to the OST file, select and copy all the contents to be converted with your mouse.
    4. Go back to the new PST file, then paste all the contents into the PST file

    That will do the conversion.

    You can also perform the conversion by export the contents of the OST file to a PST file by following the instructions at:

    http://office.microsoft.com/en-001/outlook-help/export-outlook-items-to-an-outlook-data-file-pst-HA102534110.aspx

    Second, if you can access the Exchange server containing the account data for the OST file, then you can use Export-Mailbox command to export the data into a PST file, similar to convert your OST file into a PST file. Below is the article about doing that:

    http://technet.microsoft.com/en-us/library/bb266964.aspx
    http://technet.microsoft.com/en-us/library/cc535123.aspx

    Third, if you cannot access the OST file via Outlook, neither can you access the Exchange Server, then you can refer to Outlook MVPs' website discussing about this issue:

    http://www.slipstick.com/problems/pst-repair/convert-an-exchange-offline-file-ost-to-a-personal-file-pst/

    Forth, there are many third-party OST to PST conversion tools you can try, below is a list of them:

    https://www.datanumen.com/exchange-recovery/compare.htm

    Nearly all these tools provide a free trial so you can try first to see if a tool works before purchase it.

    Good luck!
