    Welcome to ITKE, lstaff836! I would suggest you check out Microsoft's inbox repair tool (scanpst.exe). I think that will solve your issue.

    These are two different types of files. An .ost file is the data file that is created when you log onto MS Outlook. A .pst file is a personal file that you create to move all of the email messages that you want to keep. So, there is no need to convert an .ost to a .pst.

    5. Finally click on Finish button
    Note; But this option will only work if your Outlook profile is connected with Exchange Server.

    Yes, you can convert OST to PST. You can do it manually by using some manual methods and if you're not that much technically sound are afraid of making mistakes, you can try for a software for this. Initially, I also used an OST to PST Software. It was good. You can give a try.
