Yes, it is completely possible to export Thunderbird emails with attachments into PST format correctly, especially when using a professional backup and migration utility like the SysInfo Thunderbird Email Backup Tool. The software is designed to maintain the integrity of mailbox data during conversion, meaning emails, attachments, inline images, formatting, and metadata remain unchanged throughout the process.
This is particularly important for businesses and professionals who rely on email attachments for daily work. During the migration, the tool keeps the original folder hierarchy intact, so folders such as Inbox, Sent, Drafts, and custom folders appear in Outlook exactly the same way they were organized in Thunderbird. In addition, users can choose selective migration options, apply date-range filters, and decide whether they want to include or exclude attachments.
Because the software supports bulk mailbox export, it becomes a practical solution for users dealing with large Thunderbird profiles who want a secure and organized way to move their emails into Outlook PST format.
