Data migration sometimes can be really difficult to deal with. And when it is to be implemented on emails, it reaches a whole new level of complexity. There are different kinds of email file formats and each of them is sophisticated in its own way. This poses a problem for users, especially those who are fairly new to email migration.

In this article, we will be dealing with the question i.e., how to convert Thunderbird to PST. Although Thunderbird and Outlook are regarded as two of the most popular email clients, both of them lack any native means of conversion between them. Moreover, incompatibility between their data files(MBOX and PST) further complicates this issue. Which is why we have come up with practical manual and automatic method that can be implemented to perform this conversion easily.

Know How to Convert Thunderbird to PST Manually

No matter what the reason is for conversion to Outlook PST, the method to gain required results remain the same. In the following manual solution, we will be taking advantage of EML format, which is supported by both Thunderbird and latest version of MS Outlook (2010 & above). The steps are as follows:

  1. Transfer Thunderbird messages to EML Manually
  2. Move the EML files back into MS Outlook for Free

Now starting with the solution:

Step 1: Transfer Thunderbird messages to EML Manually

  1. Run the Mozilla Thunderbird application and select the mailbox folder in which the emails to be exported reside
  2. Now select the required messages in this mailbox folder. Use Ctrl+A for selection of all the email messages
  3. Next, right click on any of the selected emails and hit the Save As option
  4. Create and select a folder on local system to save the Thunderbird emails as EML files.

Step 2: Move the Converted Email files into Outlook for Free

MS Outlook 2010 and newer versions support direct import of EML files via manually dragging and dropping emails. But do note that this may take time depending on the number of files to be imported. The steps to import EML messages into Outlook are as follows:

  1. Run MS Outlook application and create a new mailbox folder. Name it accordingly
  2. Now, open the folder containing EML files on the local system
  3. Next, simply select each and every EML file, then drag and drop them into the newly created mailbox folder.

If the ultimate goal of knowing how to convert Thunderbird to PST file is accessing emails in Outlook, these manual steps are fine enough! But if the user specifically requires PST file, then use the free native Import/export option in Outlook to gain it.

Note: For earlier versions of Outlook, users will need to drag and drop the EML files to Windows Live Mail. Then use the free native means to export these emails directly from Windows Live Mail to Outlook profile. Do note that, inline images may get converted into empty attachments after export.

Important!

Although this manual process works well and fine, it is not feasible for users having concerns such as:

Time consumption: Depending on the number of emails, the process will take time, lots of it, while both extracting emails from Thunderbird or transferring them to Outlook.

Data Integrity: Free manual conversion leads to loss of folder structure and puts the integrity of data at risk.

Bulk Conversion: Repetitiveness of this free manual process for each mailbox makes it tiresome for users and hinders the productivity during bulk export.
