How to import Apple Mail archive files in Outlook 2013? I need to import Apple Mail archived files in Outlook 2013 on Windows, but every time I open the import wizard and reach the file selection step, I cannot select the archived file. It doesn't even show in the dialog box.

I don't know what the issue is. Is it the file size issue as the archive file is large (about 7 GB) or there is any other fault?
Apple mail archive are in .mbox format which is not a supported Outlook format in windows. You cannot import this file, that's why.

You might want to look for a .mbox to .pst converter.
