Convert Mbox To Pst 📍 🎁

import mailbox from pypst import PSTMessage, PSTFile mbox = mailbox.mbox('inbox.mbox') pst = PSTFile('output.pst', 'My PST File')

pypst is incomplete (no attachments, no folder nesting, limited Unicode). Real-world emails break it. convert mbox to pst

Prioritize the Date: header. Verify after conversion: sort by "Sent" column. Pitfall 3: Folder Depth > 256 Characters Why: PST has a path length limit (including Unicode characters). Deep nested labels from Gmail (e.g., [Gmail]/All Mail/Projects/Archive/2023/Q4/Reports ) truncate silently. import mailbox from pypst import PSTMessage, PSTFile mbox

# Install dependencies (Ubuntu/Debian) sudo apt install readpst # contains mbox2pst variant pip install mbox-converter pypst Verify after conversion: sort by "Sent" column

| Source | MBOX Origin | Pain Point | |--------|-------------|-------------| | Google Takeout (Gmail) | Takeout/Mail/*.mbox | Folder structure lost if you don't use the right tool | | Mozilla Thunderbird | ImapMail/... (no extension) | Each folder is an MBOX file | | Apple Mail (legacy) | ~/Library/Mail/V5/*.mbox | macOS Sierra and earlier | | Old Unix mail servers | /var/mail/username | Single flat file for all incoming mail |

# readpst actually converts PST to MBOX. For MBOX->PST, you need: # 1. Split MBOX into individual .eml files # 2. Use import to Outlook (not pure script) mb2md -s source.mbox -d output_maildir/ Then use Outlook's "Open & Export" -> Import from another program -> Outlook Data File.

If you work with enterprise email, you’ve faced the dilemma: a legacy MBOX file from an old Unix server, Thunderbird backup, or Google Takeout export… and you need it in Microsoft Outlook’s native PST format.
