    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.

    There are several tools to do this job with cost. But if you want to do it free, you can use ‘Archiving’ to save OST emails to PST. When enable archiving, Outlook emails from OST file are saved to a separate PST file. It helps in keeping the size of the mailbox at an optimum level by saving the older mailbox items in the archive folder.

    Hi there,

    Using the Manual method, you can convert OST to PST file. But it is a little bit techie, unsafe and a long process that's why I always suggest users go with a third party tool. Shoviv OST to PST Converter is also a third party tool which has a free trial version as well.

    Hope It works

    It is needed to ask for a demo before buying a tool/ software for this purpose. Sometimes third party tools are not satisfying that what a user wants. It is better to see a demo & if it satisfies then go for buy.
