Yes, it is possible to convert MBOX files to PST while choosing how attachments are handled during the process. I was looking for a way to migrate my Thunderbird mailbox to Outlook, but I didn't always need the attachments embedded with every email. Some attachments were large enough to increase the size of the Outlook data file, so I wanted a solution that offered more flexibility than a standard conversion. After trying a few options, I found that the Aryson MBOX to PST Converter provides different attachment management options during conversion. You can keep attachments embedded within the emails, save them separately to a chosen location, or even exclude them entirely if you only need the email content. This makes it much easier to manage storage, especially when working with large mailboxes containing thousands of attachment files. Apart from attachment handling, the software maintains the original folder hierarchy, email formatting, metadata, sender and recipient information, and timestamps throughout the conversion. It also supports bulk conversion, allowing multiple MBOX files to be converted into PST in one go, which is useful if you're migrating data from several accounts at the same time.
I also noticed a few additional features that make the process more convenient. There is a Date Filter for exporting emails from a specific period, custom file naming options to organize the output, and the ability to split large PST files after conversion to keep them manageable in Outlook. Besides PST, the software also supports exporting MBOX data to formats like PDF, EML, MSG, CSV, Thunderbird, and MBOX, depending on what you need. Furthermore, the tool is compatible with all versions of Windows OS, such as 11, 10, 8, 7, and many more.
