How to Bulk Convert MSG Files to MBOX Format Without Losing Attachments?

I was also struggling to convert MSG files to MBOX format, especially when I needed to convert bulk emails along with their attachments. Outlook Direct does not support MSG to MBOX export, and sometimes attachments go missing, but the emails were becoming corrupted. Then I tried the WholeClear MSG to MBOX Converter tool. I found its interface quite simple; I just selected the folder containing the MSG files and chose MBOX as the output format—the tool accurately converted all the emails with attachments. The tool interface is simple, so no technical knowledge is required. I simply selected the entire folder containing my MSG files and chose MBOX as the output format. Its biggest advantage is that it completely preserves attachments, inline images, email headers (To, From, Subject, Date) and original formatting. The folder hierarchy also remains the same, which is quite important for email management. This tool works with almost all popular versions of Microsoft Outlook, such as Outlook 2021, 2019, 2016, 2013, 2010 and Outlook 2007.

Main Point

• This tool can transfer MSG files even without Outlook installed.
• It supports batch conversion, handling hundreds or thousands of MSG files.
• It maintains the folder hierarchy, keeping your emails neatly organized.
• The interface is simple, making it easy for even non-technical users to use.
• The full version has no size or file limitations.

Steps – MSG to MBOX Conversion

• Download and install the tool.
• Open the software and select the MSG files using the Add Files / Add Folder option.
• View the emails in the preview panel.
• Select MBOX as the output format.
• Choose the destination folder.
• Click the Convert button.

I found the free trial version quite useful. Before purchasing, I tested the output quality by converting a few limited MSG files using the trial version. This convinced me that buying the full version was worthwhile. The full version has no file limitations and handles large-scale conversions easily.
