The Thunderbird to PST Converter is a feature-rich and user-friendly software. It makes it easy for the users to convert Thunderbird emails to Windows Outlook PST format without any data loss and security issues. The software support conversion of Thunderbird files:

  • MBOX Files: Thunderbird stores all its emails and attachments in files with no extension having the same name as the mailbox folder. For example, All contents of Inbox folder will be saved in Inbox file with no extension.
  • SBD Files: Mozilla uses SBD format to depict the folder structure as created in the Thunderbird interface. For instance, if Inbox contains emails along with subfolders A & B having their own emails. Then Thunderbird will create a no extension Inbox file(containing its emails) as well as Inbox.sbd file storing no extension A & B MBOX files containing their own emails.
  • MSF Files: Mail Summary Files are created for each mailbox file along with its MBOX file. It only contains the header information and no actual data. So, instead of converting MSF file, the conversion of no extension Mailbox files is required.
