Want to move Thunderbird email data to Outlook

Hi everyone,
I'm hoping someone here can help. I've recently backed up many of my old Thunderbird emails, which are in MBOX format. Now, I want to move everything to Microsoft Outlook, but I just realized Outlook doesn't support MBOX files directly.
Has anyone here successfully converted MBOX files to PST? I’m looking for a method that doesn’t mess up the folder structure or email formatting. Free tools seem hit or miss, and I don’t want to risk losing data.
Any help or recommendations would be much appreciated!
Thanks in advance.

    If you are really looking to import MBOX files into Outlook 365, you can add your account in the classic Outlook desktop client, then drag and drop them into custom folders. But don't make the mistake of adding them to the inbox folder, you will turn it into an attachment.
