  • I found an old OST file from a previous system, but it does not open now. Outlook configuration is missing, and the account no longer exists. I just need to view the emails through a browser for reference. Any advice?

  • The old OST file is not opening, and I want to view emails with a web browser. To open an OST file in a web browser, you need to convert the OST to HTML format. This can help you to view your emails and other OST file documents in any web browser. I suggest using ToolsGround OST to HTML Converter, because it can easily convert OST files to HTML format without any data loss. This OST to HTML Converter software can easily convert Outlook OST files to HTML format, whether they are old or disconnected from the server for any reason. It supports bulk conversion and provides a preview of mailbox features. Plus, it comes with selective conversion features, so users can convert required data without wasting time on converting entire OST files. Additionally, offers a demo version for all users.
