If you are having problems while migrating from Thunderbird to Outlook, you can opt for an efficient Thunderbird Converter tool.

This software converts all Thunderbird emails including the data stored in no extension MBOX files and SBD folders.

Converting Thunderbird emails in MSG format saves each message in a separate file while converting to PST produces a mailbox file containing multiple email messages.
