Learn Where Mac OS X Mail Stores Your Emails

Apple Mail has been the standard Mac email client since the early days of macOS. It's versatile and functional, helping users stay organized and on top of their email with a seamless experience.

The location of your stored Mail messages isn't readily apparent. They’re buried in a folder in the Library, and the archive uses a .mbox file extension. Since there may be times you want to copy your email to another computer, or even back up stored messages, here's how to find and access all your stored Mail email files.

The following includes information that applies to all versions of Apple OS X Mail.
