Top Methods to Import Thunderbird Mail into Outlook 2007, 2010, 2013, and 2016

Welcome to the world of email migration! If you are using Mozilla Thunderbird for your emails and wish to switch to Microsoft Outlook versions 2007, 2010, 2013, or 2016, we have you covered. Our guide will show you how to import Thunderbird mail into your desired Outlook version easily. Following our step-by-step instructions, you can seamlessly transfer your emails, contacts, and other data, ensuring a smooth transition between the two email clients. Let’s begin your journey to a new email experience with Outlook!

Method 1: Import Thunderbird mail into Outlook 2007 Manually

This manual method contains both the sender’s details and the data. Using two email clients, Mozilla Thunderbird, and MS Outlook:

Using Mozilla Thunderbird

  1. Open Mozilla Thunderbird
  2. Locate the folder and browse for the messages from the folder or the entire folder you want to convert from Thunderbird to a different email client.
  3. Now check the messages you want to export or select the entire messages folder.
  4. Now save the selected messages using the “save as” option.
  5. Select the earlier folder to save it as an “EML file” ->select folder. Now export the message.

Using MS Outlook

  1. Open MS Outlook 2007
  2. Go to the menu option and select New Folder from the available tab.
  3. Now you are required to name the folder. Name it accordingly, and choose the OK button to create the file.
  4. Select the new folder that you recently created. As the name suggests, it would be empty.
  5. Select the emails that you exported from Thunderbird.
  6. Now import the messages into the middle of the newly created folder. Drag and drop the messages from Thunderbird, and in this way, your process is completed.

Following the above, you can save your Thunderbird emails into an Outlook PST. However, the above procedure is quite lengthy and requires technical expertise. However, you can also check out the additional methods that we have provided.

Method 2: Another Solution to Transfer Thunderbird to Outlook PST

Follow the below steps to transfer MBOX emails into PST. However, we suggest following the instructions carefully, as data loss may occur:

  1. Download and install Mozilla Thunderbird.
  2. Configure your account with the necessary credentials (email address and password).
  3. Use the email client’s import feature to bring in the MBOX files. 
  4. Locate the Import option in the client’s menu and choose the MBOX file you want to import.
  5. Organize the imported emails into appropriate folders to ensure a cleaner transition to PST format.
  6. Once the MBOX files are imported and organized (if necessary), look for an option to export or save the emails in PST format.
  7. Select the destination folder where you want to save the PST file and proceed with the export process.
  8. The export process may take some time, depending on the number of emails and their size.
  9. After the export, verify the PST file to ensure all emails are correctly transferred and organized.
  10. Finally, open Microsoft Outlook and use the “Import” option to import the PST file into Outlook.
  11. Select the appropriate options to ensure a smooth import.

The above manual method is another way to transfer MBOX files into PST, but it is only partially safe.
