Outlook keeps all your emails in a PST file, and you need Microsoft Outlook to open it. The problem starts when you want to share those emails with someone who doesn’t use Outlook. That’s where things get a bit difficult. Outlook does have an option to save emails as HTML. HTML files can be opened in any browser, so they’re much easier to share and access without needing Outlook. In this blog, we’ll go through different ways to convert PST to HTML. We’ll cover both manual methods and a professional EmailProHelp PST Migration Tool.
