It could surprise you to learn that Mozilla Thunderbird, a great email client, can easily handle several email accounts. Many users do not know how to import MBOX files into Thunderbird, even though it is free and has a big user base. Whether that you're working with an old backup file or an MBOX file that you obtained from email services like Gmail, Thunderbird has you covered. We will provide you a dependable way to import MBOX files into Thunderbird in this post, using both a free and a paid option.

Types of MBOX Files You Can Handle

There are multiple different types of MBOX files. The MBOX types that the techniques will support are listed below:

  • A file that ends in .mbox (such as an Apple Mail MBOX file)
  • A Mozilla Thunderbird MBOX file without an extension
  • A Google Mail MBOX file with several mailboxes
  • Files (such as Eudora or Pocomail files) having an .mbx extension

Any of these files can be imported into Thunderbird by following the instructions.

How Can I Add an MBOX File to the Thunderbird App?

Solution: Users can use any of these methods to easily move MBOX data into Thunderbird desktop:

  • First, get an add-on from the Thunderbird shop.

Method 2: Use Thunderbird Importer software to carry out the import procedure.

Alternative Strategy: How can I upload MBOX files into my Thunderbird IMAP account?

The specific stages are as follows.

Before we start, please be aware that an MBOX file cannot be added straight to a Thunderbird email account that uses IMAP. The file has to be exported using the methods in a POP-based account or the Local Folders mailbox. If required, the data can then be moved to the IMAP-based account.

Method 1: Install the Thunderbird Add-on to Import MBOX Files

  • To begin, launch Thunderbird and select the Add-ons and Themes option from the Tools menu.
  • Press the Alt key to bring up the menu if it's not displayed.
  • In the Extensions tab's Search field, type "importexporttools."
  • Locate ImportExportTools NG in the search.
  • Click the extension and Add into Thunderbird.
  • After installation, right-click on the mailbox folder in which you wish to import the data.
  • Choose selective MBOX Files under ImportExport Tools NG > Import MBOX Files.
  • Tap on the Open button after selecting the MBOX files.
  • And voila! The task is finished.

Please be aware that these processes were conducted using Thunderbird version 102.4.0, which has been changed to Thunderbird 128.6.0esr. Additionally, they should work with earlier versions. Just make sure that, depending on your Thunderbird version, you select either the ImportExportTools NG or the older ImportExportTools add-on.

Despite the fact that this approach is free, some users would rather employ specialized tools. This is because there have been cases when the manual procedure has changed the imported emails' information. This is a serious issue for professionals. As a result, many people choose to utilize professional tools like the one we'll talk about below rather than take this chance.

Technique 2: Use Professional Software: Import/Shift MBOX file into Thunderbird

It is imperative to use trustworthy BLR MBOX Converter software to preserve the email attributes, information, and attachments throughout the procedure. A user may quickly move MBOX files in bulk into a Mozilla Thunderbird email account with this program.

Steps to Import MBOX to Thunderbird

  • Launch the BLR MBOX Converter.
  • Add MBOX files to programs.
  • Choose the MBOX folder that you wish to add to Thunderbird.
  • All of your selected additional MBOX files will be processed and shown by the program.
  • Bring the chosen MBOX file or files into Thunderbird.
  • As the tool chooses the default directory for Thunderbird's data file, begin the procedure in the following window.
  • To view MBOX files, launch Thunderbird. Lastly, launch Thunderbird to see the files in the "Local Folders" section.

Extra: IMAP Account Import Procedures

Two techniques for importing MBOX files into local folders or POP3 accounts were discussed in the previous section. Technically, you cannot import your MBOX file into your Thunderbird IMAP account directly. We will thus outline the procedures in this section for migrating your data from local folders or a POP3 account to an IMAP account.

Using one of the aforementioned techniques, users can import MBOX files into the Thunderbird local folder or POP folder. After that, you may transfer the imported data into your IMAP account by following the instructions below. So you're done with your work!
