MBOX file format

MBOX is a specialized email storage format used by a number of email clients on Mac, Linux and Windows PC. The mailbox file format has never been turned into a standard and currently has a huge number of variations. Neither of them is natively supported by Microsoft Outlook and they all need to be converted for compatibility with any version of Outlook 2021, 2019, 2016, 2013, 2010, or older.

Mbox to Outlook Transfer software is a compact, fast and convenient tool that solves this problem and allows users to import MBOX files of any size from any platform to Outlook – either directly to an existing profile or to a standalone PST file. The program saves users time and money. They can import MBOX to Outlook directly on their own, without outsourcing task to convert mbox to pst to expensive external services or busy IT departments.

We did our best to simplify the User Interface of the program to the extent where it can be used by anyone: from a complete novice to a professional with years of experience in data conversion and recovery. As a result, the export of a typical email archive to popular file format takes no more than a minute and just a few mouse clicks.

Getting ready for email conversion

Before starting the email conversion process, you need to take care of the source data — i.e., export it — first. If you want to migrate from a Mac (Apple Mail), copy the Mbox files to the PC where Mbox to PST Transfer tool is installed. Use a USB stick, an external HDD, a Dropbox/Google Drive * folder or any other method of file transfer.

Tip: Please do not use the Cloud drives as a source for the conversion. Copy your mailbox files locally and use the local source instead.

Method 1: How to Import Mbox to Outlook Automatically

Below are the steps to import MBOX directly to your Outlook account, presented in a step-by-step guide. If you’re interested in an automatic mode for importing MBOX to Outlook, please follow these instructions:

Step 1: Start the MBOX to Outlook Converter

Clicking the desktop shortcut or select it from the Start menu. If your Outlook version is 32-bit, you have to execute the 32-bit Transfer tool, otherwise you have to use the 64-bit Transfer tool. Download the free trial version if you have not already done so.

Step 2: Select the source folder

Click the button with three dots (…) to open mbox files location in the mailbox folder selection dialog. Browse to the mbox folder containing the source files and select it. Selected path will be displayed in the source folder field. Alternatively you may paste the patch to the source folder into the text field or drag the mailbox files you want to convert into the list of email containers.

Use Scan Folder button to search each mailbox file

Step 3: Scan the Source Folder

Click the “Scan Folder” button to start searching for MBOX files in the source folder and subfolders. The names of the found files will be displayed in the “Email Containers” area. The program will open mbox file and check the format integrity automatically.

Use Scan Folder button to search each mailbox file

Step 3.1 Configure the program options (optionally)

You are now almost ready to start importing mbox files to outlook. Before you do that, you may want to modify some of the following options available in the “Options” menu:

  • Check that the email client is running – if this option is enabled, the program will check if MS Outlook is running. If it is at the start of conversion, the program will ask you to close it to prevent potential access conflicts when you import mbox to outlook directly.
  • Remind to disable antivirus – if the option is enabled, the program will notify the user that all anti-virus tools like Norton or Kaspersky must be closed or temporarily turned off during data conversion. If they are still on, they can interfere or even interrupt the process, so your attempt to import MBOX to Outlook may fail.
  • Use an internal format processor – choosing this option will enable an alternative data parser. Choose this option if the standard parser didn’t work for your MBOX files as well as expected.
  • Convert email encoding – the program support mbox files saved from Unix apps and Mac Mail for Mac OS and this option helps to convert email encoding to make emails converted to PST format to be readable on Windows OS.
  • Prompt to select the Outlook profile – this option is available in the “Import to Outlook” mode and enables you to select the destination Outlook profile in the special dialog box for your converted data when you importing MBOX files into Outlook.
  • Target Outlook folder [Prompt to select the Outlook folder; Inbox] – sets the default folder for converted emails. You can set it manually for every conversion or set it to “Inbox” as the default choice for future conversions.
  • Split output PST file – this option creates a new PST file when the current Outlook data file reaches the specified size. This allows you to create multi-volume PST files. These PST files can be used separately after conversion. Use this option if you want to import mbox file into several smaller PST files.
  • Open PST file in Outlook – when the program finishes migrate mbox files into Outlook, it opens the resulting pst file and makes it accessible in Outlook. Different Outlook versions may or may not allow to open PST file automatically. If PST file was not opened automatically, you may need to use manual method: in Microsoft Outlook click File menu > Open & Export > Open Outlook Data File…
  • Open PST file location – when the program finishes migrate mbox files to Outlook PST file, it will open the File Explorer window and select the created PST file. If you then plan to import PST data into an existing Outlook profile, you may need to disable this option.
  • Create nested folder structure in Outlook – the program will follow each subfolder under the specified source folder and create the Outlook folder based on the directory name where the mailbox file is located. Free demo version imports up to 10 emails per mailbox folder.
  • The “Mode” menu of Mbox to Outlook Transfer lets you choose the conversion mode: Outlook profile or PST file. Depending on your choice, you will import MBOX files either to an Outlook profile or a PST file. (“Save to PST” mode is active by default. And you have to use this mode if your Outlook is configured to use IMAP or Exchange Server accounts.) Additional mode allows to export emails from MBOX emails to EML files. The program creates a directory with the same name as the original mbox file and export mbox data in this folder as eml files.

Step 4: Start the Conversion

You are ready to proceed to file conversion – when you actually import MBOX files, that is. To do this, click the “Import” button. If you enabled the “Remind to disable antivirus” option, the program will prompt you to temporarily disable your anti-virus to avoid potential conversion issues. Click OK to accept it and continue. You may also see an MS Office configuration selection window now – just leave everything “as is” and click OK to proceed.

You will now see a dialog for selecting a destination for exported emails – pick an existing folder or create a new one, then click OK to start email conversion and import mbox files into Outlook. If you chose to save data to a PST file, the process will be identical, save for the destination folder selection step – instead, you will need to specify a folder on your computer. Note that you can only use local folders to store the PST file because the Outlook object data model does not support network locations.
In “Save to PST File” mode, you can also select PST file which already exists, in this case the selected file will be appended to the imported data.
