One of my old Outlook profiles stopped working after a system crash, and I only had the OST file left. I tried a few manual ideas but nothing really worked. Then I used DataVare OST to PST Converter. It read the OST file without any trouble and created a PST that opened normally in Outlook. My folders and emails were where I expected them to be, so I didn't have to reorganize anything afterward.
