Introduction

In general, Outlook PST files are used for the storage of emails and other mailbox information. However, users may need to move this data to email clients that work with the MBOX format, such as Thunderbird, Apple Mail, Eudora, Netscape, and other supported applications. So MBOX is helpful when you are looking to migrate Outlook email data to some other email environment.

Conversion of PST to MBOX is a sensitive task especially when the source contains a large number of emails, attachments, folders or important business correspondence. A proper checklist can help users to prepare the source file, select the required data, perform the conversion and verify the resulting MBOX file.

Based on the capabilities and workflow described for the WholeClear PST to MBOX Converter, this guide provides a practical before, during, and after conversion checklist.

Preparation Checklist Before Conversion

☐ 1. Find the Right PST File

Locate the Outlook PST file that you want to convert. If you have more than one PST on your computer, look at the file names and locations before you choose one. The source page says that the application can handle different types of PST files like ANSI, Unicode, archived and password protected PST files. It also supports different editions of Outlook PST files.

☐ 2. Making a PST Backup

Before you start any migration, make a backup copy of the original PST file. Keep the backup in a different location so that you always have access to the original data should you need to re-do the conversion. Avoid modifying or deleting the source PST during the conversion process.

☐ 3. Verify PST Health

Verify that the PST can be accessed properly. The product documentation states very clearly that the utility is designed to work on healthy PST files and it doesn’t support the damaged or corrupt PST files. If the PST is corrupt, repair it before performing the migration.

☐ 4. Identify the Destination Email Client

Decide where the converted MBOX data will ultimately be used. The product page says it supports MBOX-compatible applications like Thunderbird, Apple Mail, Eudora, Netscape, Entourage, SpiceBird, and others. Knowing the client you are sending it to helps to format the output accordingly.

☐ 5. Decide Which Data Needs Conversion

Do we need the whole PST file or just the data from specific mailboxes? If you have years of email in the PST, converting everything could generate a lot of unnecessary output. The application provides the preview of PST’s folders and subfolders before conversion so that user can verify the available data.

During Conversion Checklist

☐ 6. Install Software Conversion

Install PST to MBOX application on supported Windows Computer. The product documentation states it is built for Windows platforms and cannot be installed on Mac OS.

☐ 7. Add PST File

Run the application and click on the browse option to select the required PST file. The workflow documented starts with launching the software and searching for the PST database.

☐ 8. Open the PST Database

Preview before conversion. The application scans the PST and shows the folders and subfolders in a tree structure so that users can see the mailbox data available before proceeding.

☐ 9. Choose Required PST Data

Select the data you want to transfer and browse the folders you have. This is especially important if you are working with a large PST file with Inbox, Sent Items, Drafts, archives and other folders.

☐ 10. Verify Email Formatting and Properties

You need to review important email data before conversion. The product information says the conversion is designed to preserve email formatting and attributes such as sender, recipient, CC, BCC, subject, hyperlinks, inline images, text layout and other email elements.

☐ 11. Confirm Attachments Required

If the PST has emails with attachments, list few example emails which can be verified post conversion. PST emails can be exported to MBOX along with attachments, as per the product page.

☐ 12. Choose an Output Location

Choose the folder where you want to save the MBOX file. Using a separate destination may make the converted data easier to find and review.

☐ 13. Begin the Conversion

Once you’ve checked the PST, preview, required data, and output location, start the conversion. The documented workflow is to select the location of the MBOX file and click the option for conversion.

☐ 14. Follow the process

Do not close the application or move the source file until the conversion process is complete. If you see any unanticipated messages or errors, record the details for troubleshooting.

Conversion Verification Checklist

☐ 15. MBOX File Analysis

Once the conversion process is complete, locate the generated MBOX file and ensure it is saved to the desired location.

☐ 16. Amount Check Mail

Where possible, compare the converted data to the expected contents of the mailbox. The difference doesn’t necessarily equate to a problem. Maybe some data or selected folders were omitted during conversion.

☐ 17. Open the MBOX in Destination Client

Open the email application and import the MBOX file. The source documentation says about a general process to open the client, select the import option and select the MBOX file.

☐ 18. Sample Review Emails

Open sample emails from different folders and verify that the message content is displayed correctly. If possible, look at older and newer messages.

☐ 19. Verify Attachments and Inline Content

Open emails with attachments, hyperlinks and inline images. Verify availability of key content after migration.

☐ 20. Check Folder Organization

Verify if the mailbox data is still logically arranged. It specifically states that folder and subfolder structures will be preserved in conversion.

☐ 21. Retain the Original PST

Do not delete the original PST immediately. Maintain the backup until the MBOX migration has been fully reviewed and the destination email environment has been verified to contain the necessary data.

Final Checklist for PST to MBOX Conversion

Before you call the migration done, check:

☐ Correct PST file is chosen

☐ PST backup (original)

☐ Healthy and accessible PST

☐ Destination email client recognized

☐ Required folders checked

☐ PST preview confirmed

☐ Properties validated via email

☐ Attachments chosen for testing

☐ Output destination selected

Conclusion

With PST to MBOX conversion, the Outlook email data can be accessed by a large number of email applications that support MBOX. But a successful migration isn't only about converting the source file, but about meticulous preparation and verification.

This checklist can assist users in avoiding conversion issues and performing a systematic review of their PST data before, during and after a migration. The process can be further streamlined by using a preview-based workflow, support for attachments and email properties, folder preservation and support for multiple applications supported by MBOX. The recorded process also allows users to complete the conversion within few steps like adding PST, previewing its contents, selecting output location and converting the data.

The best practice for users who are planning a PST to MBOX migration is to back up the original PST, review the source data, perform the conversion, test representative MBOX emails, and retain the original data until the migration is fully validated.
