How to Migrate Thunderbird to Outlook

Migrating emails from Thunderbird to Outlook is not always straightforward due to differences in their underlying file formats. Thunderbird uses MBOX to store email data, whereas Outlook relies on the PST format. This incompatibility can make the migration process tricky for users unfamiliar with the technical details.

#Method 01: Manual Method to Transfer Thunderbird Mails to Outlook

Here is the manual method to migrate Thunderbird to Outlook. Before we move to the steps, make sure you have a Gmail account (with IMAP enabled). Also, you should have access to both Thunderbird and Outlook on your computer. Along with your email account credentials for both Thunderbird and Gmail.

#Step 01: Prepare the Gmail Account for IMAP Access

IMAP allows email clients to sync with the Gmail server, and any changes you make are reflected across all devices. Follow these steps to enable IMAP in Gmail:

1. Log into your Gmail account: Open your Gmail inbox in a web browser.
2. Click the gear icon in the top-right corner and select See all settings.
3. Navigate to the Forwarding and POP/IMAP tab.
4. Under the IMAP Access section, ensure that Enable IMAP is selected.

7. Finish Setup: Click Done to complete the setup.

Thunderbird will now sync with your Gmail account, allowing you to access your emails through IMAP.

#Step 03: Move Thunderbird Emails to Gmail (via IMAP)

To move your Thunderbird mail items to Gmail, simply copy or move them into your Gmail inbox or folders. It can sync the emails to your Gmail account and they can be accessed from any email client (including Outlook).

1. In Thunderbird, navigate to the folder that contains the emails you want to transfer.
2. Select the emails or entire folders you want to move to Gmail.
3. Right-click on the selected emails and choose Move To >> Gmail Account.
4. If you want to keep the folder structure, you can create corresponding folders in Gmail (within Thunderbird) and move the emails there.

#Step 04: Set Up Gmail in Outlook

Now, you’ll set up your Gmail account in Outlook, so you can access the emails you just transferred. 

1. Launch and open the Outlook application on your computer.
2. Go to File >> Account Settings >> Account Settings.

Outlook is now connected to your Gmail account via IMAP, which means all emails from Thunderbird (moved to Gmail) will appear in Outlook.

#Step 05: Sync Thunderbird Emails in Outlook

Once your Gmail account is set up in Outlook, you can access the emails you moved from Thunderbird. Since Gmail uses IMAP, all your email folders and messages should sync automatically between Gmail and Outlook.

1. Depending on your internet speed and the number of emails, it can take some time for Outlook to fully sync with Gmail and display all your messages.
2. After syncing, you’ll find the emails you moved from Thunderbird in your Gmail inbox or the corresponding folder within Outlook.

By using Gmail as an intermediary with IMAP, you can migrate Thunderbird to Outlook. However,  this method is quite lengthy and complex to accomplish the task. Further, we will mention some pointers which you should be aware of while using the manual method.
