MBOX Editor for Mac, iPhone and iPad

Need help or found a problem? Email admin@yenpi.com. Please include your device, its system version and the app version (shown in the App Store or in the app's About window on Mac).

Which files can it open?

Flat mbox files, such as those from Gmail Takeout or Thunderbird; Apple Mail .mbox export folders; and Outlook for Mac archives (.olm), with each Outlook folder kept as a label.

Will it change my original mailbox?

No. Mailboxes are opened where they are and only read. Your edits are kept as a list of changes, and the only files the app writes are the exports you ask for.

Where do my exports go?

On Mac, to the location you choose when you export. On iPhone and iPad, to the Files app under MBOX Editor › Exports; you can also share an export straight from the app.

Why are images missing from some messages?

Remote images are blocked by default so a sender cannot tell that a message was opened. Load them for a single message from the banner above its body, or change the default in Settings.

Can I edit mailboxes on iPhone or iPad?

Not yet. On iPhone and iPad you can open, search, read and convert mailboxes; deleting, moving and relabelling messages is available on Mac.

The app is using a lot of storage.

Indexes make reopening a large mailbox instant. Clear them in Settings (Index caches); they are rebuilt the next time a mailbox is opened. On iPhone and iPad, Settings also lists past exports, which you can delete.

Reporting a problem with a specific file

Describe the file — where it came from, its size and roughly how many messages it holds — rather than attaching it. Mailboxes contain personal mail, so please do not send one unless we ask and you are comfortable doing so.
