Switching from Thunderbird to Apple Mail can seem daunting, especially if you have years of emails, contacts, and other data stored in Thunderbird. This migration is common if you have recently bought a new PC or Mac and want to transfer thunderbird emails from Windows to Mac or a New Computer.
If you are also looking for migration but do not know how to get this done without any error then this guide will help you. We will walk you through the process of migrating your emails and other important data from Thunderbird to Apple Mail.
Why Migrate to Apple Mail?
Apple Mail is the default email client for macOS, offering seamless integration with other Apple products and services like iCloud, Calendar, and Contacts. It also boasts a user-friendly interface and advanced search capabilities, making it a popular choice among Mac users.
Step-by-Step Guide to Migrating from Thunderbird to Apple Mail
1. Export Emails from Thunderbird
- Launch Thunderbird: Open Thunderbird and select the email account you want to export.
- Select Emails: Click on the folder containing the emails you wish to migrate (e.g., Inbox, Sent, etc.).
- Export Emails: Right-click on the selected folder and choose "ImportExportTools NG" (a Thunderbird add-on that you may need to install first) and then "Export all messages in the folder" > "MBOX format."
- Save Files: Choose a destination folder on your computer to save the MBOX files. These files contain your email data.
This MBOX file can used in various applications apart from Apple Mail. You can also import MBOX in Gmail, SeaMonkey and other MBOX compatible emailing applications.
2. Prepare Apple Mail for Import
- Open Apple Mail: Launch Apple Mail on your Mac.
- Set Up Account: If you haven’t already set up your email account in Apple Mail, go to "Mail" > "Add Account" and follow the prompts.
- Organize: Create folders in Apple Mail where you will import the emails.
3. Import and open MBOX file into Apple Mail:
- Go to File > Import Mailboxes: In Apple Mail, select "File" from the menu and then choose "Import Mailboxes."
- Select MBOX Format: Choose "Files in mbox format" and click "Continue".
- Choose the MBOX Files: Navigate to the folder where you saved your exported MBOX files from Thunderbird.
- Import: Select the MBOX files or folders you want to import and click "Choose". Apple Mail will import the emails into a new folder named "Import" under "On My Mac."
4. Organize Imported Emails
- Move Emails: Once the emails are imported, you can move them to your desired folders within Apple Mail by dragging and dropping.
- Check for Missing Emails: Review the imported emails to ensure everything has transferred correctly. If any emails are missing, repeat the import process for those specific files.
5. Migrate Contacts and Calendars
- Export Contacts from Thunderbird: In Thunderbird, go to the Address Book, select the contacts you want to export, and choose "Tools" > "Export." Save the contacts as a VCF file.
- Import Contacts to Apple Mail: Open the Contacts app on your Mac, then go to "File" > "Import" and select the VCF file.
- Calendar Migration: If you need to migrate calendars, export them from Thunderbird in ICS format and import them into the Calendar app on your Mac.
Troubleshooting Tips
- Large Email Folders: If you have large folders, consider splitting the export into smaller batches to avoid issues.
- Duplicates: After importing, check for duplicate emails and contacts, which can occur during migration.
- Missing Attachments: Ensure that email attachments have also migrated. If they’re missing, try exporting and importing the emails again.
