User Query: I have many old stored PST files, and I am not able to open them in a browser or send them to someone without needing Outlook. Is there a free way to convert them to HTML without losing emails or attachments?

Summary: PST files can be an issue if you are not using Outlook anymore. You can’t just open one in a browser or send it to someone and expect it to work. HTML is a lot more practical. Any browser can open it, no software needed. So if you want your old Outlook emails to actually be readable without installing anything, converting PST to HTML is the best option. In this blog, we’ll go through a manual way to convert PST to HTML and also look at the MacSonik PST Converter Tool for when the manual route feels like too much work.

Why Do Users Convert PST File to HTML?

  • HTML works in any browser without extra software, and you can open PST only in Outlook.
  • Some users just want to read old emails without reinstalling or purchasing Outlook again.
  • HTML format makes it simple to upload emails to a website or internal company portal.
  • Migrating to a new email client is smoother when emails are already in a readable HTML format.
  • Legal teams sometimes need emails in HTML for documentation, review, or compliance-related purposes.
  • Old PST files from retired accounts are easier to archive and access when saved as HTML.
