I am facing a serious issue with my Outlook data. My laptop suddenly crashed last week due to a hard drive problem. I managed to recover most files, including my Outlook OST file; however, Outlook now refuses to open it. Every time I try to import it, I get the error message: "This OST file cannot be opened because it is not associated with your current profile." I had all my project communication, client reports, and attachments stored inside that OST. The worst part is, my Exchange profile was company-based, and I no longer have server access. I just want to view those old emails again - not necessarily in Outlook, but at least in a readable format. Someone from my team told me that I can convert the OST file to HTML format so that each email can open directly in a browser like Chrome or Edge. That sounds perfect for me since I only need to read or reference old messages. Can anyone please suggest a safe method or tool that can help me convert my old OST file to HTML without requiring Outlook or Exchange connection? I want to make sure no data or formatting gets lost.
