It’s certainly not unusual to want to store your data only on locations over which you have full control—not some company’s cloud, even if that’s Apple. Macworld readers Bob and Barbara migrated off other mail services to iCloud specifically to download messages directly and to avoid poor performance they were perceiving. They thought macOS Mail and iCloud would be a better match.
In the Export to Archive File (.olm) box, check the items you want to export, and choose Continue. In the Save As box, under Favorites, choose the Downloads folder, and click Save. Once your data has been exported, you'll get a notification. For information on how to access the data that you've saved in an Outlook for Mac Data File (.olm), see Import email messages, contacts.
But they’re in a pickle, because they’re seeing iCloud storage fill up (Bob) or become full (Barbara), and they don’t want the messages there at all. When they log into their mail, they want any email to be moved from the server to their Mac.
Apple’s Mail and most email clients on every platform and from every third party optimize their defaults settings around leaving mail on a server. That’s the modern way, where we can reach the same mail storage on any device, as well as through Web mail.
However, it’s possible to avoid all this. You just have to change a view settings and rethink how you file mail once you’ve dealt with it. You can archive messages on a single Mac and store them there without leaving a copy on the server. (You’d better be making backups, Time Machine or otherwise, or you’ll be sunk if your drive fails.)
Your Inbox will always remain on the server. The Inbox is essentially a window into messages that have arrived and you haven’t processed. You make one change in settings and one change in behavior for everything else.
In Mail in macOS, follow these steps:

Download Mac Mail For Windows
- Select Mail > Preferences and click Accounts.
- Select iCloud in the list at left.
- In the Account Information tab, set Download Attachments to All. (The only reason to avoid this if you get frequent large attachments in messages you delete without needing those attachments.)
- In the Mailbox Behaviors tab, for each mailbox popup menu, select a mailbox listed under On My Mac. (If no mailbox exists, you need to create it from the Mailboxes sidebar.
- Apple's mail on 10.11 and older will download all the mail that the server tells it about. The macOS 10.12 mail has a setting to optimize mail storage that might store header information for all mails, but not download the body and attachments of older emails.

- Preparing Mac Mail messages: If you have the modern version of the Mac Mail (v.10), you do not need to find the location of the Mac Mail data store. Instead of that you may save Mac Mail messages into mailbox files using the “Export Mailbox” function. Do the following to export Mac Mail messages: Run Mac Mail and expand the folders tree.
Now all the standard Mail behavior will result in messages being downloaded or stored on your Mac.
On the behavior side, create all the mailboxes you need under the On My Mac section of the Mailboxes list, and then as you receive email in your Inbox, file those locally into those folders. That removes the messages from the mail server, leaving it stored only on your Mac.
