    I'm trying to do the same thing but Mail crashes when I try to import mbox file from Outlook.

     

    I tried booting is safe mode but this did not work as well.

     

    Mail creates a folder but it is empty when I re-start the program after the crash.

     

    Anyone have any suggestions?

    Eric, I went back and used a trial version of Outlook to create and export out a PST file of my emails. Then I downloaded PST Easy Convert from the Apple App store ($5) and used that program to convert directly into Apple Mail.  It worked perfectly.  Hope this helps.

    I ran into this as well but solved it.

     

    Some background: The problem is that the output .mbox file has the wrong line endings and the mail import can't handle it. Windows normally ends lines with a carriage return and linefeed while a unix system (Mac is unix under the covers) uses only a linefeed. The cause of the crash (I suspect) is that the .mbox output by Outlook has only carriage returns. You could buy an app from the store to translate an OLM file, but it can be done for free if you're willing to try a few commands at the terminal.

     

    Steps

    1. Make a new folder and copy your .mbox files in. They should be the only files in this folder. The lines beneath assume you have this folder on your desktop and it's called "importing'.
    2. Copy the folder to a new location as a backup if you can't recreate them easily.
    3. Open the 'Terminal' app (found in Applications/Utilities/ in the Finder).
    4. Run these commands (I suggest you copy / paste):

      cd ~/Desktop/importing
      perl -pi -e 's|\r|\n|g'  *.mbox

    This may a while to process all of the .mbox files if they're large, but when it's done, you should be able to open the .mbox files with the TextEdit app or just run the import:

    • Open Mail
    • File -> Import Mailboxes...
    • Select "Files in box format'
    • navigate to Desktop, select the 'importing' folder
    • click 'Choose' and...
    • revel in the glory!
