Features of PST File Converter

The SysCurve PST Converter helps you export Outlook data to MBOX, EML, MSG, or HTML with a clear, selective workflow. Convert only what you need and create formats that work across email clients and archives.


Convert PST to MBOX for cross-client migration

Convert PST to MBOX for clients like Thunderbird, Apple Mail, Eudora, and SeaMonkey. The tool extracts the mailbox data and outputs clean MBOX files ready for import. Ideal when moving away from Outlook.

Convert PST to EML for individual emails

Export each message as a separate EML file for individual access. This format works with Windows Live Mail, Outlook Express, The Bat!, and many review tools. Great for eDiscovery and message sharing.

Convert PST to MSG for Outlook items

Create MSG files that open directly in Outlook. This is useful for archiving single items or moving messages between Outlook profiles. Each MSG includes the full content and attachments.

Convert PST to HTML for browser viewing

Export emails to HTML for browser-based access on any device. The output is easy to open and search without Outlook installed. This is a solid option for long-term archives.

Preview PST data before export

Load the PST and preview folders and messages inside the tool. Verify the scope before you export. This reduces mistakes with large, multi-year archives.

Selective folder conversion

Choose specific folders or subfolders to export. Targeted conversions are faster and create smaller outputs. Useful for project-based migrations or focused exports.

Folder structure and metadata accuracy

Folder hierarchy carries over to the output so navigation feels familiar. Headers, dates, and read status travel with each message. This supports audit and review workflows.

Direct PST reading without Outlook

The converter reads PST mailbox data directly, so Microsoft Outlook does not need to be installed for export. This is useful on review systems, archive workstations, and machines where Outlook is not configured.
