A native Mac archive workspace

From forgotten backup to working mail.

Built for very large mailboxes

Messages appear while MBox Office discovers the archive. Interrupted indexing can resume from its last safe position, and the complete mailbox never needs to sit in memory.

Search as deeply as you need

Find mail by sender, recipient, subject, date, attachment, Gmail label, folder, or message text. Choose fast header search or build a reusable content index.

Open archives you already have

Works with Google Takeout, Thunderbird, Apple Mail export packages, standard MBOX files, MBX files, common format variants, and legacy text encodings.

01 · Find

Dig up the email you thought was gone.

Search sender and recipient addresses, dates, Gmail labels, folders, attachments, and full message text. Structured filters such as has:attachment, from:, after:, and mailbox: help narrow even enormous archives.

02 · Recover

Keep the messages, contacts, and files that matter.

Export selected messages or the complete mailbox as standard EML. Save every unique contact in a VCF file, extract attachments in bulk, print messages or save them as PDF, and safely add EML files to an archive.

03 · Organise

Make a giant mailbox manageable.

Split a mailbox by target file size, year, sender, or mailbox label. Preview the result before writing anything, and run long operations in the background with pause, resume, and progress reporting.

04 · Restore

Put important mail back.

Restore selected messages or migrate the complete archive to any standard IMAP mailbox. Connections use verified TLS, destination mailboxes can be selected or created, and remembered passwords stay in the macOS Keychain.

Private by default

Your archive stays on your Mac.

Opening, indexing, searching, splitting, and exporting happen locally. No Technichor account is required. HTML is sanitised, JavaScript is disabled, and remote images remain blocked until you choose to load them.
