It’s expedient to always retain a backup of your emails from the Thunderbird email client, more so for the following reasons:
- Constricted file size for folders: Mailbox folders have a 4GB limit for each account. And there is no way to allocate more space and increase quotas. Users are forced to remove old messages and attachments. Alternatively, they can specify a new folder for storing mail.
- Corrupted folders and emails: This is a common occurrence with Thunderbird, where specific folders, such as Trash, can become corrupted. Even individual emails may become damaged, making it impossible to open them. Smart users back up their email folders for this reason.
- System malfunctions: For POP accounts that retain their copy of the email folder on the computer, there is the risk of losing access to the emails if the computer becomes damaged. That’s why it’s critical to permanently save Thunderbird emails as a backup on a removable storage device or the cloud.
We’ll recommend three techniques to help with the issue of how to back up Thunderbird to an external hard drive.
Advantages of Saving Thunderbird Emails to Hard Drive
Why should you back up Mozilla Thunderbird emails to the hard drive? Taking this move affords you many benefits:
- overcome file size limitations without losing your old emails and attachments;
- have a saved copy of the email folder in case you need to recover the program;
- foster better security if the computer or program becomes corrupted by malware;

How to Backup Mozilla Thunderbird Emails to External Hard Drive Manually?
Let’s look at three leading solutions that effectively resolve the issue of how to back up thunderbird emails to an external hard drive.
These methods are easy to implement. Remember, Thunderbird has no native function to back up individual folders or messages. You actually copy the Profile Folder to move it or back it up.
Manual Method 1: Via Import-Export Add-on in Thunderbird
Are you faced with the prospect of backing up individual email folders from Thunderbird to an external hard drive, for instance, Inbox or Sent? There is a convenient add-on that you can use.
- Add the ImportExportTools add-on to Thunderbird.
*See how to install an Add-on in Thunderbird.
- To access ImportExportTools, select a Mail Folder, for instance, Inbox, and right-click on it.
- Choose the export function you want from the available selections: Export Folder, Export all messages in the folder, etc.
- When exporting all messages, you’ll need to choose a format. The Add-on will suggest suitable file formats. For instance, it’ll recommend EML format, CSV, or plain text format for text-based messages. For messages with attachments, you’ll see formats that accept attachments, for instance, HTML and CSV.
- Set the destination directory.
Note that it’s possible to back up thunderbird email to the hard drive on MacBook using the same add-on. You may also export Thunderbird emails into MBOX format.

Let’s deal with the issue of how to back up a copy of Thunderbird’s profile to an external hard drive. It is a bit different from the last solution that dealt with exporting individual messages and folders. You’ll not need any installs for this method as it requires copying the Profile Folder used by the email client to store its information.
- In Thunderbird, click on the Menu Icon > Help > Troubleshooting Information.
- On the page, you’ll see the Application Basics section that lists some facts about the program, such as its version. You will also spot the Profile Folder.
- Click on the Open Folder button.
- It will launch the Profile Folder, where Thunderbird stores your profile information.
- Go back to Thunderbird and close it, leaving the Profile Folder open.
- Proceed as follows; in File Explorer, go back three levels, for instance, from AppData/Roaming/Thunderbird/Profiles/Msigjspshgs to AppData/Roaming.
- Select the Thunderbird folder, and copy it. It will include all the profiles.
- Simply copy the folder to the removable devices or online backup folders such as GDrive or Onedrive.
- Wait for the transfer to complete.
- When restoring the data, you only need to replace the Thunderbird folder with the one you copied.
