Hello friends,
My Outlook stopped syncing because of a profile issue, and now I'm stuck with an orphaned OST file. I heard converting OST to PST can bring back the data.

I found a tool on Inspired Data Care that seems promising. It's easy to use and doesn't need any Outlook profile or Exchange server to work. I tried it, and it recovered everything -- mails, attachments, even calendar entries!

Here's the tool link:
