Also, how enterprise teams handle it at scale, and how the DRS Softech PST Converter Tool gets it done safely without any data loss.
Quick Solution to Convert PST File to HTML
You can convert a PST file to HTML by exporting emails from Outlook using the “Save As HTML” option. Or by using a professional PST converter tool for bulk and accurate conversion. Here is how you can perform it:
- Download the DRS Softech PST File Converter.
- Load your PST files to convert and click Next.
- Preview and select them to convert. Press Next.
- Then, pick HTML as the Saving format.
- Lastly, apply features and click Convert.
Why Convert Outlook PST to HTML?
- No Outlook needed: Once converted, anyone can open and read the emails in a browser.
- Easy sharing: HTML files are lightweight and easy to share, attach, or upload.
- Legal and compliance use: Lawyers, auditors, and HR teams often need to present email records as readable documents. HTML is one of the cleanest formats for this purpose.
- Long-term archiving: HTML is an open format that will still be readable years from now.
- Furthermore, works on any device: Once your emails are in HTML, you can open them on any computer, tablet, or phone without worrying about software compatibility.
Methods to Convert PST File to HTML
Depending on your situation and the volume of data you need to convert, there are two main approaches:
- Manual Method
- Enterprise Method [PST to HTML Converter]
Method 01: Manually Save PST Emails to HTML format
The manual method uses Outlook’s built-in Save As feature. It works for converting individual emails, but it becomes very slow for large mailboxes. Make sure Outlook is installed and your PST file is loaded. If it is not showing, go to File > Open & Export > Open Outlook Data File and browse to your PST file.
Steps to Convert Your PST to HTML Manually
- Open Outlook and make sure your PST file is visible in the left folder panel.
- Double-click the email you want to convert to open it in a new window.
- Now, go to File in the top left corner of the email window.
- Then, click Save As and choose a destination folder on your computer.
- In the Save as type dropdown, select HTML.
- Click Save. The email saves as an HTML file at your chosen location.
- After that, open the saved file in any browser by double-clicking it.
- In the end, repeat this process for every email you want to convert.
Limitations of the Manual Method
- You can only convert one email at a time: no batch option exists in Outlook.
- For large mailboxes, this process takes days of manual work.
- Attachments are saved separately in a messy folder next to the HTML file.
- The original folder structure does not carry over.
- Additionally, if the PST file is corrupted, Outlook may refuse to open it entirely.
