Struggling to Convert OST to PST: Need Working Solution

[Jamesnoah091]

I am having trouble converting my OST file to PST format. My Outlook profile got corrupted, and now I only have the OST file left. I tried using the manual export method, but since the OST is not connected to the Exchange server anymore, it does not let me open or export the data. Is there any reliable way or tool to convert the OST file into PST so that I can access my emails, contacts, and calendar again?
