How to Migrate from Thunderbird to Outlook?

In this post, we’ve mentioned ways on how to migrate from Thunderbird to Outlook. We’ve explained some manual methods with stepwise instructions to move Thunderbird mailbox items to MS Outlook. In addition, we’ve mentioned about a specialized MBOX to PST converter software that can help you migrate from Thunderbird to Outlook quickly.

Thunderbird, developed by Mozilla Foundation, is a free cross platform email client that is compatible with Windows, Mac and Linux operating systems. Thunderbird stores all the mail items such as emails, attachments, etc. in MBOX files on local storage.

Microsoft Outlook offers various additional features and outperforms Thunderbird in some key areas such as security, personal information management, and support for add-ons. That’s why organizations often migrate from Thunderbird to Outlook.

However, the migration isn’t easy as you can’t directly export Thunderbird mailbox data, which is in MBOX files, to Outlook. The most efficient and easy way to transfer Thunderbird mailbox data to Outlook is by converting MBOX file into Outlook importable PST format. However, there are some other methods that you can use to manually migrate mail items from Thunderbird to Outlook.
