Thunderbird & Outlook – A Technical Perspective

Mozilla Thunderbird is a desktop email client that saves its data in MBOX files. A closer look at these files will reveal that they don’t have any extension. Users may also see several SBD files in the Thunderbird local storage directory. This SBD folder is responsible for maintaining the sub-folder hierarchy of Mozilla Thunderbird. The underlying MBOX files are present as inbox, draft, sent, etc., i.e., one file for each mailbox. As far as the contacts are concerned, Thunderbird provides an option to export them directly in CSV files.

On the other hand, Outlook is the most popular email client among business as well as home users to manage emailing functions. Outlook is a part of Microsoft Office which offers to save its entire data in PST file format. So that the entire data of Outlook such as emails and attachments, contacts, notes, tasks, calendar entries, etc. is present in PST file format. Although Outlook can store everything in its PST file, it also provides a way to import the contacts file in CSV format.
