If you just started using the Mail app on your Mac, you may want to import a mailbox file from another app. This can give you a great jumpstart on tracking and answering emails during the transition.
At the same time, you might want to export a mailbox from the Mail app for use elsewhere. Maybe you’re trying out a new email app and want to use your existing messages intact.
Either way, the Mail app on your Mac makes it easy to both import and export mailboxes and this tutorial shows you how.
Import a mailbox to Mail
You can import a mailbox from Apple Mail or as a file which may or may not be named with the MBOX format.
1) Open Mail and click File > Import Mailboxes from the menu bar.
2) Mark either Apple Mail or Files in mbox format and click Continue.
3) You’ll then be prompted to locate the file and then click Choose.
No matter which option you select for the import, you’ll see a confirmation once the data is loaded. Then you’ll have a new mailbox labeled Import in the On My Mac section of the left-hand sidebar.
Export a mailbox from Mail
Remember, you’ll be exporting an entire mailbox as MBOX format. If you’d rather export a particular email as a PDF from the Mail app, that’s a different process and our other how-to can help you with that.
1) Open the Mail app and right-click or hold Control and click on the Mailbox you want to export.
2) In the shortcut menu, select Export Mailbox.
3) Select a destination location for the MBOX file for your mailbox and click Choose.
You should then see that MBOX file in your chosen location. From there you can import it to another supported app.
Wrapping it up
There’s nothing easier when moving data like emails and mailboxes to and from the Mail app than the import/export feature.
