There are so many options available for transferring the Mozilla Thunderbird to Outlook. And here I am going to discuss three possible methods to move the data from Thunderbird MBOX to Outlook PST.

1- IMAP feature for Moving Thunderbird to Outlook

2- Drag and Drop process to Convert Thunderbird to Outlook

3- Using a Thunderbird to Outlook Converter

Method 1: IMAP feature for Migrating Thunderbird to Outlook

Use the following steps to convert the Thunderbird to Outlook.

Step 1: Firstly configure your Gmail account to the Mozilla Thunderbird 

Before using this step by step process you need to connect your email account to the Thunderbird with the IMAP Configuration. And here I am going to connect the Gmail with TB, then follow all these given solutions.

1- First login to your Gmail Account and go to Settings.

2- In this window Enable the IMAP/POP under Forwarding and POP/IMAP option >> Save Changes.

3- After that launch the Mozilla Thunderbird and click the Email option under the setup account.

4- Now type Your Name, Email Account, and Password >> hit Continue to for connecting the Gmail to Thunderbird.

5- Further, select the IMAP checkbox and enter the necessary incoming & outgoing server details >> Re-text. And once it completes then click on done.

The account has been successfully configured with Thunderbird. And after that create a new folder and move the data from Thunderbird to Gmail.

Step 2: Connect that Gmail account with the Outlook 

1- Open the Outlook after that add the account by clicking on File>> Add Account option.

2- After that Check on the Manual setup or additional server types >> Next and select the POP or IMAP option >> Next.

3- Put the account details with the IMAP account type and enter the Incoming or Outgoing Mail Server. After that go to More Settings.

4- Go to the Outgoing server and check on the My outgoing server (SMTP) requires authentication.

5- After that put the incoming and outgoing server port (993 & 587) then click on ok >> Next.

6- Now you will get the confirmation message then close it.

7- Once you successfully configure your account you can import Thunderbird files data to Outlook 2019, 2016, 2013, 2010, 2007, and etc.

Note: This manual process is time-consuming and very complicated to understand for non-technical users. And with this process, you can import the orphaned, corrupted and deleted items from the Mozilla Thunderbird to Outlook.

Method 2: Drag and Drop process to Convert Thunderbird to Outlook

Step 1- First run the Mozilla Thunderbird program on your PC. And open the mails which you want to migrate from Thunderbird to Outlook.

Step 2- Now choose single or entire emails as per your requirement and right-click on it >> select Save As option and save the entire message in EML formats.

Step 3- After that open, the Microsoft Outlook 2019, 2016, 2013 & 2010 and create a new folder inside it. And again drag the thunderbird emails, which saved in EML format.

Step 4- Finally the Thunderbird emails successfully import into Outlook from the Mozilla Thunderbird.

Note: With the manual method might be your data can be lost or corrupt, and it not able to assure full migration and has fewer savings options after conversion.
