MBox office is a simple MBox viewer for the Mac (above 10.7).
It lets you restore your archived .mbox archive to any IMAP supported email provider.

You should be able to open mbox files using File -> Open.

It might take a while if it is a large file, please wait until the progress bar stops. It might take a few minutes to read the whole file. If the progress bar stops, that means the whole file has been loaded onto the system. If the progress bar is still going, the whole file has not been loaded.

- Tested with iCloud, Gmail, Google Apps, Microsoft Exchange. It should work on most email accounts.
- Supports multiple email accounts
- Native Email Browsing interface where you can restore specific emails
- Batch email restore. Select All emails and click on "Restore Selected Emails"
- You import individual emails in .eml format to your existing .mbox file. You can use all the above mentioned features with it.

Does the job

Managed to import and view a 329MB MBox file after a few minutes of “processing” with no problems. Nice, clean interface.

My only suggestion is to add an email search function.

Exactly what needed

I was a bit hesitant to purchase this app, but for $2.99 gave it a shot anyway. For me it works just nice and is exactly what I needed. You can open Mbox archives by File -Open and point to your MBox archive. Archive opens up in a simplified e-mail look alike window and I was able to browse through my archived e-mails. It sure saves time and mess which you can sometimes create by importing old archives into Mail app.
Possibility that app remembers size of the window so you don’t have to resize them every time
Drag and drop of e-mail archive into the window to bypass File - Open

If you have a lot of e-mail archives, this one is a time saver. Well worth 2.99

Quick Export, Worked fine!

I started a contract job with another company. I needed to get everything they had previously sent me over to outlook on their system. Exported about 250 emails to eml format. Worked fine!
