Thanks. We'll let you know when a new response is added.

If your MS Outlook and MS Exchange server is in working conditions, you can use the built-in ‘Export’ option in MS Outlook to export the OST file into PST files.

Another option is “Drag-and-Drop items from Offline Folder File to PST“. If none of these methods work, you can employ an OST to PST Converter. Using this, you can easily convert OST to PST.
