Managing email from Thunderbird to Outlook environment is a challenging task for novice users, even if you don't have complete knowledge of this conversion you will easily fail it.
So we need a principled tool that directly exports Thunderbird to Outlook without any complexity. However, we also suggest a manual process from Thunderbird to Outlook but in some cases because they can contain errors.
Mozilla Thunderbird & its mail format
Mozilla Thunderbird is an open-source email-management application that allows the user to save the email in MBOX and Maildir file formats. But MS Outlook does not support MBOX or Maildir files so we need a solution to transfer data from Thunderbird to Outlook.
Now if we choose the manual process first then we can export some emails but not large mailboxes. Still, I would like to provide you a complete guide on Thunderbird to Outlook migration so first I am going to tell you the manual conversion.
Manual preparation & migration for Thunderbird to Outlook
To start the conversion task, first, we have to install Outlook Express on the same pc then we can follow the below method.
Phase (A)
- Launch Mozilla Thunderbird and install the Import Export Tool add-on.
- Right-click on a folder which you want to import into Outlook >> Import-Export-Tool NG >> Export all messages in the folder >> Choose EML file format.
- Select or Create a new folder and save data in .eml file format.
- Launch Outlook Express and create a new folder then drag all EML files in it.
Phase (B)
- Launch Microsoft Outlook and Go to the File tab.
- Choose the import-export tool option in the list then select “import internet mail and address” and press the Next button.
- Select “Outlook Express” option and import mail checkbox >> Next >> Finish.
Congrats, if you get the mailbox safe in Outlook otherwise I want to suggest a third-party tool that is quite simple and 100% secure.
