Import Address book in Microsoft Outlook from Mozilla Thunderbird

Over the years, with the popularity of Microsoft Outlook growing exponentially, a lot of people have exported their existing email accounts to Outlook. But no one denies the fact that email migration is a tedious and challenging process to complete even when it involves two popular email clients like Thunderbird and Outlook

However, a problem with manual process is that you cannot import all mailbox items from Thunderbird to Outlook at once. And therefore, you need to perform multiple steps to import other mailbox items such as Thunderbird contacts into Outlook manually.

But sometimes you may want to know a method to only import contacts from Thunderbird into Outlook and add them to your Outlook contacts list.

In this post, we have discussed a few methods to import Thunderbird address book into Outlook. These methods will not only help you import address book from Thunderbird into Outlook but also help you import all other mail items at once.

Why Export Thunderbird Contacts to Outlook?

  • Outlook is far superior to Thunderbird when it comes to features and compatibility with different platforms
  • Managing users’ personal information is much easier with Outlook
  • Outlook is more user-friendly and flexible than Thunderbird
  • Outlook allows configuring multiple email accounts within a single interface simultaneously

A Few Important Notes about Thunderbird to Outlook Migration

If you need to switch your emailing client due to any of the above reasons, here are a few points you should keep in mind:

  • Thunderbird uses MBOX format data file to save mailbox contents whereas Outlook uses PST for the purpose. Hence, the best way to migrate or import Thunderbird address book into Outlook is to convert the MBOX file to PST format
  • As there is no direct manual method to convert entire MBOX file to PST format, emails and contacts need to be exported separately
  • To export Thunderbird contacts to Outlook manually, you must export the Thunderbird contacts to CSV file and then import the CSV into your Outlook account
