How to convert MBOX to PST

Josh Smith

Aid4Mail can quickly and accurately convert MBOX files to a PST file without a hassle. Aid4Mail will preserve the entire email including the header data, body and all email attachments. Aid4Mail can also preserve the folder structure if you have multiple MBOX files from an email account.

Aid4Mail is fully Unicode-compatible and preserves more crucial data, visible and hidden, after conversion than any of its competitors.

Visible data:

  • To, From, Date and Subject fields
  • Status information (Read, Replied, Starred, etc.)
  • Message text
  • Message formatting
  • Diacritical marks / accented characters (like é, ô and ç)
  • Non-Latin characters (for example ??)
  • Embedded images and other media
  • Attachments and their filenames
  • Folder/label hierarchy

Hidden data:

  • Metadata in the email header
  • Server relay information
  • Digital signing

Aid4Mail integrates a sophisticated mbox parser that is used to extract emails from mbox files. It is able to handle a large variety of mbox and MIME format errors that can be found within mbox files. As a result, Aid4Mail can find emails that other products either miss or incorrectly merge with the preceding message. This means there is almost no data loss when using Aid4Mail for the conversion of mbox files.

Aid4Mail also provides additional options to customize the output of the emails in the PST file. Some of those options include:

  • Ability to customize the folder structure of the emails when converting to the PST file
  • Limit the size of the PST file being created. If the limit is reached, a new PST file is incremented and remaining emails are converted to the new PST file
  • Create a new base folder in the PST file where all the contents of the MBOX file will be converted to.
  • If you need to add emails to an existing PST file, Aid4Mail can append or add emails from an MBOX file to a PST file you already have.
  • Filtering options to select only the folders you need to convert from the MBOX file. Of course if you need to convert all the emails from the MBOX file (even hidden folders inside the MBOX file), Aid4Mail has you covered as well.

Aid4Mail provides you with the option to convert MBOX to PST without Outlook being installed on the machine. By default, Aid4Mail will use Microsoft Outlook as it is more reliable and we are experts with Outlook and the underlying MAPI technology. If you don’t have MS Outlook installed on the machine, simply use our alternate method in the Aid4Mail GUI for the MBOX to PST file conversion.

Aid4Mail has no issues when converting large MBOX files. Aid4Mail thrives on being able to provide a solution on the market that can process any size MBOX files. If you you are already want more information on an Aid4Mail license that can convert MBOX files to PST, take a look at our Aid4Mail Converter license here.

Aid4Mail can search entire emails including the header, body and all attachments from every email. Aid4Mail can even search files contained in zipped files (that are attachments).

Also with the Investigator license, you have the ability to process multiple MBOX files concurrently at the same time to speed up a project that might entail converting multiple MBOX files to PST files. We have many clients that use Aid4Mail to process through hundreds of MBOX files per month. It’s a huge advantage for them to have the flexibility and full power of Aid4Mail to process multiple different MBOX files concurrently to different PST files. You can find more information about our Investigator license here.

Although this article covers converting MBOX to PST, Aid4Mail is far more than just an MBOX to PST conversion program. Aid4Mail supports many additional file formats like OST, OLM, PST, MSG, Outlook Profile, EML, Apple Mail, Maildir, Google Takeout, Google Vault exports, Mimecast exports, IMAP accounts and more. You can also convert MBOX files to other file types like MSG, EML, PST, CSV, TSV, XML, HTML and Plain text. You can find more information here.

Let’s now go through a step by step tutorial in Aid4Mail to convert an MBOX file to a PST file.

  1. Under “Source” select “MBOX file (generic mailbox)” and then specify the location of your MBOX file(s). Source format selection
  2. Under “Target” select “PST file” and then provide the location of where you want to save the PST file that Aid4Mail will create. Target format selection
  3. Next you can specify a specific folder inside the PST file where the MBOX file data will be saved by adding the folder name under “Location in PST file”. For this example, Aid4Mail is set to save the emails and folder structure in the “Jim mbox emails” folder in the PST file.Select base folder in PST file -If you need to limit the size of the PST file being created, use the “Limit PST file size:” option. I set mine to 50GB as that is the default size set by Microsoft Outlook.Limit PST file size
  4. Finally under “Filter”, you can use the “Folder selection” tab to select only the folders (MBOX files) you want to convert. As you can see, my parent folder contains three MBOX files. I have only selected the Jim folder to process. Folder selection
  5. After all your settings are set to your preference, click on “Run” to convert the MBOX file to an Outlook PST file.
