  • Hi Omar,

    Unfortunately this is not the correct forum to ask about Exchange 2010.  But you are in luck!  You can go to the Exchange Server forum and post your question there.

  • Hi,Omar

    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. 


    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. 


    Third, you can try to convert OST to PST via Outlook VBA . 


    Hope this will help. Good Luck!
