mccb

mccb migrates Outlook PST files to IMAP mailboxes, CalDAV calendars and CardDAV address books, from a web dashboard. It is built for batches of mailboxes and very large PST files (resumable uploads).

Start here:

• Install mccb with Docker Compose and sign in.
• Migrate a mailbox: add a server, add accounts, upload a PST, run.
• Pause, resume and retry: how an interrupted import continues without duplicates.

mccb is MIT licensed, with no paid edition. Read Known limitations before relying on it.
