How to convert MBOX to PST (without data loss)

Aid4Mail is the best Mbox to PST converter software on the market. Aid4Mail provides you with a high quality solution to import Mbox to Outlook. Compared to competing tools:

  • Aid4Mail is faster.
  • More accurate with no data loss.
  • Offers more control over the conversion process.

If you don’t have Aid4Mail yet, you can use the free trial version or purchase a low-cost 2-week Aid4Mail Converter license.

Mbox files are a common email storage format used by popular products like Mozilla Thunderbird, Google Takeout and Google Vault. Although the format is simple, it’s prone to data corruption. Aid4Mail is one of the rare tools that can repair the damage correctly and recover emails that competing tools miss.

Aid4Mail can convert your mail to a PST file with or without Microsoft Outlook installed. However, you will get better performance when Outlook is present. Aid4Mail can also faithfully restore your folder structure.

Please follow the steps below to convert mbox files to PST with Aid4Mail. For any setting that’s not specifically mentioned, you can either use the default (preset) value or consult the Aid4Mail 5 User Guide for details. You can open it from Aid4Mail by pressing the F1 key.

Step 1: Open Aid4Mail’s settings

Aid4Mail settings: Session name set is to "John Doe Mbox to PST"; the Source and Target sections have been expanded but not yet set; the Filter section has not yet been expanded.

  1. In Aid4Mail, select the Settings tab.
  2. Update the Session name to so it describes for the task at hand. In this example, we will be converting John Doe’s Mbox files to a PST file so we’ve entered John Doe Mbox to PST as the session name.
  3. Below the session name there are three sections: Source, Target and Filter. Each can be displayed or hidden by selecting the +/- symbol next to the section heading. This tutorial requires them all to be displayed.

Step 2: Set Mbox files as your source

Source settings for the Mbox format

  1. In the Format list, select Mbox files.
  2. Set the Location of your Mbox files, either writing it directly in the field or by using the Select button to browse your file system. Set a single Mbox file, or a folder containing Mbox files, or a folder whose hierarchy (anywhere below it) contains Mbox files. For this example, we’ve set a folder called JohnDoe.
  3. Choose whether to Remove journaling envelope if your email files are journaled.

Step 3: Set a PST file as your target

  1. In the Format list, select PST file.
  2. Choose whether to Process using Outlook. This means using Outlook’s internal engine (MAPI) to create the PST file (it has no effect on the reading of your source mail). Using Outlook’s engine is faster but requires Outlook to be installed on the same computer as Aid4Mail. If you don’t have Outlook installed, keep this option off.
  3. Specify where you want your PST file to be saved. You can write directly in the field or use the Select button to browse your file system. You can also set a Password to protect the file.
  4. Optionally, set a folder Location in PST file where your converted mail will be saved. In our example, we have set a folder called Converted mail. This folder doesn’t exist yet but Aid4Mail will create it.
  5. Select an option for the Folder structure of the exported mail. Usually you’ll want to keep it the same as the original, so choose Same as source folder structure.
  6. Decide whether to Limit PST file size. In our example, we’ve set it to 50GB which is the maximum file size allowed by Outlook by default. Once the file has reached its limit, subsequent emails will overflow into a second PST file. And once that one’s full, then into a third, and so on.

Step 4: Set your filter (optional)

  1. Under Folder filtering, pick Folder selection. Your Mbox folder structure will appear in the box below.
  2. Select the folders you want Aid4Mail to process. The others will be skipped.

Step 5: Run your Mbox to PST conversion

Select the Run button or Session > Run from the menu. Aid4Mail will convert your chosen Mbox files to PST. It will automatically open the Progress tab so you can monitor what’s going on. Once finished, you will find full reports in the Progress log and, if relevant, the Error log.

Step 6: Open the PST file in Outlook

You can do this by selecting File > Open > Outlook Data File from Outlook’s main menu (older versions of Outlook may use different menu names).

That’s it!

We hope you found this tutorial helpful in showing you why Aid4Mail is the best tool for exporting Mbox to PST. As shown above, Aid4Mail can convert multiple mbox files to an outlook pst file while preserving all the mbox emails. Once completed, the PST file can be uploaded to MS Outlook or Office 365. Again, Aid4Mail makes it easy to import Mbox to Outlook by first converting it to a PST file.

If you have Mbox mailbox data from Apple Mail, Aid4Mail has no problem converting the Apple Mail mbox files to the Outlook PST format. Aid4Mail can also export emails to other target formats such as EML files for uploading to other email applications.
