You can either manually or professionally convert OST to MBOX (https://www.migrateemails.com/blog/convert-ost-to-mbox/). To do the manual process, first export your OST data from Outlook through Outlook's Import/Export utility. Then you can import that PST file in an email client such as Thunderbird, which has support for MBOX. Finally, you can store your emails in Thunderbird down as MBOX files.
Now the conversion of OST data to MBOX can be carried out manually and would be time-consuming. To achieve this conversion, you would need to manually install Outlook and Thunderbird, go through multiple steps, and also stand a chance of losing some information in the process. You might also not save all the crucial metadata or attachments, particularly of bigger size.
MigrateEmails OST to PST Converter (https://www.migrateemails.com/ost-to-pst-converter.php) is a great software when exporting PST data from Outlook OST to MBOX. This software is widely known for its performance and efficiency while exporting OST files into other files. If users work with these tools, then they can export OST files to MSG and, many others including PST, MBOX, EML, EMLX, CSV etc. The MigrateEmails utility also exports OST file formats to Office 365, Gmail, Thunderbird, Amazon WorkMail, etc.
Steps to Convert OST to MBOX Files:
1. Download, Install, and Execute the MigrateEmails OST to PST Converter tool on your computer.
2. Select the option Single file/ Multiple FIles and click the Next Button.
3. Click on the option Select files. Select the OST file from your systems and click on the Open button.
4. Choose the file and press the Next button
5. Once this is done, a new window will open under the option Saves/ Backup/ Migrate as an option to choose the MBOX file format.
6. Press the option Path to Save and click on the Convert button.
7. Finally, the OST to MBOX conversion would be done, and now you are asked to click on the Download Report button in order to download the data.

Converting an OST file to MBOX format is not possible directly using Microsoft Outlook, because Outlook does not support exporting OST files to MBOX. One manual workaround is first to export the OST data to a PST file and then convert the PST file to MBOX using an additional tool. However, this indirect method is time-consuming, requires Outlook to be configured appropriately, and increases the risk of data loss, especially when dealing with large or orphaned OST files.
The easiest and most reliable way is to use a professional OST to PST Converter Tool (https://marketplace.microsoft.com/en-us/product/saas/blrtools1765275669342.blr-ost-tool?tab=Overview). This type of tool allows you to directly convert OST files into MBOX format without needing access to the original email account. It supports bulk conversion and preserves emails, attachments, folder structure, and metadata. For users looking for a trusted solution, BLR Tools provides an easy-to-use OST to MBOX converter that ensures accurate, secure, and hassle-free conversion.
