MBox Office opens Gmail exports from Google Takeout, Thunderbird mailboxes,

MBox Office opens Gmail exports from Google Takeout, Thunderbird mailboxes,
Apple Mail exports, or any large MBOX archive on your Mac. Start browsing while
headers are discovered, search the archive, recover attachments, export
messages, or put useful mail back in a new account.
BUILT FOR LARGE MBOX FILES
MBox Office progressively reads mailbox headers instead of loading the complete
archive into memory. The first messages appear while discovery continues. If a
long scan is interrupted, MBox Office can resume from its last safe position.
FIND THE ONE EMAIL
Search by sender, recipient, subject, date, attachment, Gmail label, folder, or
message text. Choose basic header search for a quick pass or build a content
index when you need to search inside messages.
RECOVER WHAT MATTERS
• Read plain text and sanitized HTML email
• Open, save, or bulk-extract attachments
• Export selected messages or the whole mailbox as standard EML
• Export unique sender and recipient contacts as one vCard (VCF) file
• Split a large MBOX by size, year, or mailbox label
• Add EML messages to an archive safely
• Print messages and open several archives in separate windows
PRIVATE ON YOUR MAC
Opening, indexing, searching, splitting, and exporting stay on your Mac. No
account is required, and there is no subscription. Scripts and unsafe embedded
content are removed, JavaScript is disabled, and remote images remain blocked
until you choose to load them.
WORKS WITH THE ARCHIVES YOU ALREADY HAVE
• Gmail and Google Takeout MBOX exports, including Gmail labels
• Thunderbird and other standard MBOX exports
• Apple Mail .mbox export packages
• .mbox and .mbx files
• Common MBOX variants, line endings, and legacy text encodings
RESTORE WHEN YOU NEED IT
Restore selected messages or the complete archive to a standard IMAP mailbox
over verified TLS. Choose or create a destination mailbox, follow progress, and
review individual failures. Saved passwords are protected by the macOS
Keychain. Some providers require an app-specific password.
MBox Office is for old backups, email migration, account recovery, project
archives, and anyone who wants to make a large MBOX useful again.
