  • During large-scale email migrations, PST files act as an intermediate between MS Outlook and Thunderbird.

Manual Way to Import Outlook PST to Thunderbird

In this method, we will use the Outlook email client to import PST into Thunderbird. Outlook will serve as an intermediary by exporting the PST data. 

Follow the step-by-step process to carry out the conversion:

  1. First, launch the MS Outlook application.
  2. Then, click on the File tab and choose Open & Export > Import/Export > Outlook Data File (.pst).
  3. After that, browse and select the PST file that you wish to import. 
  4. Now, again, go to File > Add Account > Manual Setup > IMAP. 
  5. Next, choose an IMAP-supported email account and complete the setup process.
  6. In the Outlook navigation pane, drag and drop the emails from the PST file to the IMAP account folder.
  7. Then, configure the same IMAP account in Thunderbird.
  8. Once added, Thunderbird will automatically download their emails. 

Limitations of the Manual Method

  • The process to convert PST to Thunderbird will not work if the PST file is corrupted or damaged.
  • The IMAP protocol takes several hours or even days to sync thousands of emails from PST files. 
  • Also, if the internet speed is slow, IMAP syncing will become slow.
