As for the answer, first, you need to understand that Microsoft has no obligation to keep track of all the email formats used globally and provide a way to import them into Outlook. After all, PCV is the proprietary format of the MozBackup application. It is neither a practical nor reasonable scenario.

Logic Behind PCV to PST Conversion

MozBackup allows you to create a backup of several email clients like:

  • Mozilla Thunderbird
  • Mozilla SeaMonkey
  • Spicebird Mail
  • Netscape Mail
  • Postbox Mail

What it actually does is compress the profile folder that contains all the mailbox data like emails, contacts, calendars, etc. And later save them in their own PCV format.

This PCV file is simply a modified ZIP file. So, it is easy to extract data from the PCV file and import MozBackup to Outlook. All you need to do is use a PCV to PST Converter.

Note: The reason we are suggesting a converter is that Outlook does not support the MozBackup PCV files. And there are no official Microsoft tools to get this done. Read the article to understand how easy our method makes the entire conversion process.
