Converting MBOX to PST becomes essential when users want to move from MBOX-based email clients to Outlook, because MBOX file data can't be accessed in Outlook. We have two methods to convert MBOX to PST: manual and third-party solutions. First, we explain the manual technique, and later, we explain the automatic solution. 

This approach works, but is more complex. It involves using Thunderbird and Outlook together.

Steps:

1. Open the MBOX file in Thunderbird
   • If needed, use the "ImportExportTools NG extension.
2. Export Emails as EML Files
   • Select emails >> Right-click >>  Save as .eml files.
3. Import EML Files into Outlook
   • Drag and drop the .eml files into a folder in Outlook.
4. Export to PST

• In Outlook:
• File >> Open & Export >> Import/Export >> Export to a file >> Outlook Data File (.pst)

If the manual approach seems difficult to apply, you can use an automatic tool called Shoviv MBOX Converter Tool to easily convert while keeping all email data intact. This MBOX to PST Converter allows the user to convert MBOX files in batch and save the resultant file into PST, EML, MSG, and Office 365 mailboxes. The tool provides a couple of facilities that make it a more reliable tool for this conversion. If you want a detailed guide on MBOX to PST conversion, you can check out the bbloglist below:
