Yes, you can convert multiple MBOX files into a single PST file for Outlook, but Outlook itself does not support this directly. Manual methods are not practical for combining multiple MBOX files and often result in data loss or a broken folder structure.
The most effective solution is to use a professional MBOX-to-PST converter tool. Such a tool allows you to add multiple MBOX files or entire folders at once and merge them into a single PST file. During the conversion, it preserves all emails, attachments, folder hierarchies, and metadata such as sender, subject, and timestamps. You can also create separate folders within the PST to keep emails organised.
From practical experience, BLR Tools provides a secure and reliable solution for converting multiple MBOX files into one PST file, making the process fast, accurate, and hassle-free for Outlook users.
