@Aksel-Visby Aksel-Visby released this 15 Jun 21:09

First public release of ContinuMail Converter — a free, open-source, local-first tool that converts Gmail Takeout and other mbox archives into Outlook PST files on Windows, without Outlook installed and without uploading anything.

Install

Download ContinuMail Converter_0.1.0_x64-setup.exe below and run it. Windows 10/11, 64-bit; installs for the current user (no admin required).

"Windows protected your PC"? This release is not yet code-signed, so Windows SmartScreen may warn about an "unknown publisher." If you trust this source, click More info → Run anyway. Code signing is planned.

What it does

  • Converts mbox → Outlook PST with a native, from-scratch PST writer — no Outlook, no COM automation (it never takes over your mail client).
  • Local-first: makes no network connections and uploads nothing; your originals are only ever read.
  • Preserves folder structure, attachments (incl. inline images and embedded .eml), HTML bodies, dates, To/Cc/Bcc, read/unread, importance, and threading.
  • Scan & preview before converting, size-based PST splitting, live progress, and conversion reports.

Notes

  • Windows-only and mbox-only for now (EML/MSG input planned).
  • Licensed GPL-3.0-or-later. Bundles LGPLv3 PSTFileFormat (ROM Knowledgeware) and MIT MimeKit.
