Before You Start Moving Thunderbird to a New Computer
Before transferring your Thunderbird profile, take a few precautions to avoid losing or overlooking your email data:
- Create a Backup First: Keep a copy of your Thunderbird profile or important mailbox data in another safe location. This gives you a way to recover your data if something goes wrong during the transfer.
- Show Hidden Files and Folders: Thunderbird stores its profile inside the hidden AppData folder on Windows. Open File Explorer, go to View -> Show -> Hidden items and make sure hidden files are visible before looking for the profile.
- Close Thunderbird: Make your Thunderbird is completely closed on the old computer. If Thunderbird is running while you copy the profile, some files may be locked or changes may not be saved correctly.
- Check Thunderbird Version: It is also recommended to use the same or a compatible Thunderbird version on both computers. If the new computer has an older version, update Thunderbird before importing the profile.
- Make Sure There is Enough Storage: The new computer should have enough free space to hold the complete Thunderbird profile, especially if you have a large local mailbox.

Check the Transferred Thunderbird Profile
Do not assume the transfer was successful just because Thunderbird opens normally. Check the important data manually. Open several old folders, including Inbox, Sent, Drafts and custom folders and verify that the expected messages are available. Open a few older emails to confirm that their attachments and message content are accessible.
Also check your account names, folder hierarchy, address book and any locally stored messages. For a migration involving a large mailbox, compare several folders and older messages, rather than checking only the latest email. This can help identify missing local folders or incomplete profile transfer before you stop using the old computer.
