An IMAP account in Apple Mail gets a sizeable storage for 18.25 Gigabyte. It is enough to maintain a professional mailbox and store greater number of emails. When the size of the account is reached to its peak, then you should get rid of older emails and other contents. If your computer does not have such space to handle a large backup, then you can take the backup in External Hard drive. The External Hard drive can be connected/disconnected using the USB cable and it is simple to keep files in it.

You must note that in order to move Apple Mail data to external hard drive, first you have to export its emails to an MBOX file which then can be transferred to any destination drive either external or internal. Fortunately, Apple Mail facilitates a direct approach to export its data to an MBOX file. It should also be noted that MBOX files are not supposed to be opened up by every application specifically Outlook; therefore if you want your Apple Mail data to be converted and saved in PST format, you have to choose a reliable converter tool to convert the resultant MBOX file to PST format and then save it to an external hard drive. We will also highlight an efficient tool for such conversions later in this section.

Manual Method to Export Emails from Apple Mail to an External Hard Drive:

  1. Launch Apple Mail on your Mac machine.
  2. Select the mailbox folder you wish to export.
  3. Then, click Mailbox from the menu bar options.
  4. Select Export Mailbox… option from the list.
  5. Now, choose to select a destination drive to save the required MBOX file and click the Choose button.

Upon execution of the above steps, your selected data gets successfully exported to the specified location. However, this native method has limitations in terms of usability and platform of the data.

Limitation of Manual Method

The manual method to export emails from Apple Mail to an external hard drive comes with the following limitation-

  • There is only one file format available to export email data to the hard drive i.e., MBOX. Hence, you will be restricted because professional email clients like Outlook do not support the MBOX format.
  • If you are having a large mailbox file, then it will become a time-consuming process.
  • While using the manual method, there is a chance that you will encounter data loss after the completion of the method.
