Apple mail export mailbox not working

Frustrating!

The "Export Mailbox" feature in Apple Mail can be a bit finicky at times. Here are some troubleshooting steps to help you resolve the issue:

  1. Check the mailbox permissions: Ensure that you have the necessary permissions to export the mailbox. You can do this by going to Mail > Preferences > Accounts > [Your Account] > Advanced > Export Mailbox. If you don't see the "Export Mailbox" option, it might be because you don't have the necessary permissions.
  2. Check the mailbox size: If the mailbox is too large, it might cause the export process to fail. Try reducing the mailbox size by deleting some emails or moving them to an archive folder.
  3. Check for corrupted emails: Corrupted emails can cause the export process to fail. Try using a third-party email repair tool to fix any corrupted emails in the mailbox.
  4. Check the export format: Make sure you're exporting the mailbox in a format that's compatible with your desired destination (e.g., EML, MBOX, or PST).
  5. Try exporting a smaller mailbox: If the entire mailbox is too large, try exporting a smaller subset of emails (e.g., a specific folder or a date range).
  6. Check for conflicts with other apps: Other apps might be interfering with the export process. Try closing all other apps and then retrying the export.
  7. Reset Apple Mail: Sometimes, resetting Apple Mail can resolve the issue. To do this, go to Mail > Preferences > General > Reset and then restart your Mac.
  8. Check for macOS updates: Ensure your macOS is up to date, as updates often resolve issues like this.
  9. Try using a third-party export tool: If the built-in "Export Mailbox" feature doesn't work, you can try using a third-party email export tool like Elcomsoft Email Raptor or Mail Extractor Pro.
  10. Contact Apple Support: If none of the above steps resolve the issue, you can contact Apple Support for further assistance.

Remember to always back up your emails before attempting to export them, as there's a risk of data loss during the export process.
