Know More about Mozilla Thunderbird

Thunderbird is one of the best email clients in the world and comes built into Windows, Mac OS X, Linux, and Android. It is a free email client and is used by millions of people every day. Mozilla Thunderbird offers a lot of customization according to user needs.

It supports multiple accounts (GMail, Yahoo, Hotmail, etc.) and integrates with your calendar. In addition, Thunderbird comes with a lot of useful add-ons like ImportExportTools NG, Lightning, Enigmail, etc. The user interface shows the first part of a message in a light grey color. If the message contains an attachment, the attachment will be displayed as well.

Thunderbird’s single email is a .eml file extension. Users can easily import and export EML email from any location, and it also supports MBOX file format. Thunderbird creates a folder in MBOX format. You can import MBOX files and export MBOX folders to any location.

Reasons Why Thunderbird Import EML Messages not properly?

What should you do when your Thunderbird email client starts behaving weirdly? You should check your settings first. It doesn’t necessarily mean that there is a problem with your application. Maybe there may be some problem with the file that is being sent to you.

The one thing that is the same across every single email provider is the file format used to store emails. When it comes to getting Thunderbird to import the EML files, it is important to note that there are various reasons why this will not work. For instance, if the email was sent by someone else using Outlook, then Thunderbird is not going to be able to import it. Also, there are certain conditions that need to be met for the EML file to import properly. Therefore, it is important that you check the following:

  1. Ensure that the EML file is compatible with Thunderbird.
  2. Make sure that the EML file is not corrupt.
  3. Check the integrity of the file.
  4. Ensure that the size of the file is compatible with Thunderbird’s import requirements.
  5. Check the compatibility of the file with the other emails that you have imported.
  6. Check for spelling errors.

  2. Secondly, right-click on the folder.
  3. Then mouse over the ImportExportTools NG.
  4. Select “Import all messages from a directory” >> “Just from a directory” option.
  5. Now, choose the EML folder where you saved it.
