Convert MBS to TBB

Understanding the mbs and tbb file formats

MBS files are mailbox files used by email clients such as Opera Mail and Mozilla Thunderbird. They store collections of email messages in a single file, typically without attachments being separated. TBB files are mailbox files used by The Bat! email client, which organizes emails and folders in its proprietary format.

Why convert mbs to tbb?

Converting mbs to tbb is necessary when migrating emails from clients like Opera Mail or Thunderbird to The Bat!. This ensures all your messages are accessible in the new email client without data loss.

How to convert mbs to tbb

There is no direct converter for mbs to tbb due to the proprietary nature of the TBB format. However, you can use a two-step process:

1. Import the MBS file into Mozilla Thunderbird using the ImportExportTools NG add-on.
2. Export emails from Thunderbird as EML files using ImportExportTools NG.
3. Import EML files into The Bat! using Tools → Import messages → From EML format.

This process ensures your emails are transferred from the MBS format to the TBB format used by The Bat!.

Recommended software for conversion

• Mozilla Thunderbird with ImportExportTools NG add-on – for importing and exporting MBS and EML files.
• The Bat! – for importing EML files and converting them to TBB format.

Both Thunderbird and The Bat! are available for Windows and support the necessary import/export features.

Summary

While there is no one-click solution to convert mbs to tbb, using Thunderbird and The Bat! together provides a reliable workflow for migrating your email data between these formats.
