  • 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.
     Or you can use OST to PST tool from here http://www.convertemail.com/ost-to-pst.html

  • Hi,Cormosl

    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 OST to PST conversion.

     

     

    You can also perform the conversion by exporting the contents of OST file to 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/cc535123.aspx

     

     

    Third, you can try  a free OST to PST converter via Outlook VBA . Below is the article about doing that:

    Hope this will help. Good Luck!

  • As moderator “J Keystone” has suggested manual method, you can transfer ost to pst. Still converting 80,000 emails via this method won’t be a perfect choice. It does not provide any guarantee or safety for your emails while transferring.

    But it would be safe and reliable to go for a third party solution like GainTools OST to PST Converter since there is a huge number of emails. https://www.gaintools.com/ost/pst/
