Mbox 3 Catalina: Resolving Email Import Issues

Are you experiencing difficulties importing your emails from an MBox file in Mac Mail (Apple Mail) to Thunderbird? If so, you're not alone. Many users have reported similar issues with their emails disappearing or failing to import after upgrading to macOS Catalina. In this article, we'll walk you through the steps to resolve these issues and successfully import your emails into Thunderbird.

Step 1: Ensure Correct MBox Folder Selection

When exporting your emails from Mac Mail, be sure to select the correct folder containing the emails. This is often a common mistake that can cause importing issues. Make sure to select the 'mbox' folder rather than the name of the folder.

Step 2: Move Contents to Root Folder

Move the contents of the selected mbox folder to the root of your mailbox folder. This will ensure that Thunderbird imports the emails correctly.

Troubleshooting Issues

If you're still experiencing issues importing your emails, try the following troubleshooting steps:

* Check the confirmation dialogue box to ensure you've selected the correct file.

* Navigate to the folder containing the exported mailboxes and verify that the file is not 0 bytes in size.

* De-select the 'Create your Mail mail accounts in TB using instructions provided by your mail provider/ISP' option under Account settings.

Importing Emails with Import-Export Tools NG

To import your emails into Thunderbird, you can use the Import-Export Tools NG plugin. Right-click on the account Inbox and select 'ImportExportTools NG.' Then, follow these steps:

1. Select the account Inbox to import Mac Mail messages.

2. Under Account settings, de-select the options mentioned above.

Additional Tips

* Try importing your emails in batches rather than all at once to avoid any issues.

* If you're still experiencing issues, try renaming the folders removing the 'mbox' from the name (e.g., from INBOX.mbox to INBOX).

By following these steps and troubleshooting tips, you should be able to successfully import your emails from Mac Mail into Thunderbird. Remember to check for any errors or issues during the importing process and adjust your approach as needed.
