MBOX to EML Converter Software Features

What PCVITA MBOX to EML Converter Tool does with your mail archives, grouped by task.

Loads MBOX Files From 20+ Email Clients

Add files by hand or let the software fetch them from the mail client you already use.

  • Default Profile Configured

    Choose the mail application you configured and an identity. PCVITA software then fetches the MBOX files from the place where that client stores them.

  • MBOX, MBS, MBX and MSF Files

    Opera Mail, SeaMonkey, Entourage, Thunderbird and more feed MBOX files in, next to MBX, MBS and MSF files.

  • Folder Mode for Bulk Jobs

    Select a folder and every MBOX file inside it joins the job in one step. No limit applies to the number of files.

  • SBD Subdirectories and Orphan Files

    SBD subdirectory files convert along with their MBOX files. Orphan MBOX files load without the parent file.

  • Convert All Identities

    Choose Convert All Identities to export every identity of the configured profile. Select one identity to limit the job.

Add File choices for loading MBOX files
Add File screen: load a profile or browse to MBOX files

Previews Every Email Before You Save

Read the mail on screen first, then decide what becomes an EML file.

  • Folder List and Mail Section

    Folder List shows the hierarchy of all added MBOX files. Click any folder and its emails appear with their attachments.

  • 9 Preview Modes

    One email opens in 9 modes, from Normal Mail and Hex to Email Hop, HTML, RTF and Attachments.

  • Horizontal or Vertical View

    Switch the layout to match your screen and the size of the mail list.

  • Stop Button for Large Folders

    Click Stop while emails load when the first items of a big folder are all you need.

Preview panel: one email in MIME view, one of 9 modes

Names and Filters the EML Files

Settings for the EML format shape file names before one message exists.

  • Naming Convention List

    Name EML files by Subject, Subject and Date, From Subject and Date, Auto Increment, Date and Subject or Date Subject and From.

  • Delimiter for Special Characters

    Set the delimiter that replaces special characters in file names, so every EML file saves cleanly on Windows.

  • Filters in Advanced Settings

    Apply the filters on the same screen to export only the emails you need.

  • Folder Hierarchy Kept

    Keep the folder structure of the source in the destination folder, so mail stays where you filed it.

  • Selective Export

    Tick emails and right click or click the Export button to convert only those items.

  • Bulk Export

    Leave every box unticked and click Export to convert all mailboxes. Check folders to narrow the job.

Why MBOX Files Need Converting Before Other Programs Open Them

Three facts from Microsoft and Mozilla documents, with the PCVITA answer to every one.

  1. 1

    Outlook Opens EML Files Directly

    Microsoft documents that new Outlook for Windows and Outlook on the web open messages saved with the .eml extension. Drag and drop, Open with and a double click all work. PCVITA MBOX to EML Converter saves every email as its own .eml file, so those steps apply.

  2. 2

    Thunderbird Keeps Mail in MBOX Files

    Thunderbird documentation names mbox as the default for local storage and describes a folder database file that ends in .msf. PCVITA software reads the MBOX files and writes one EML file per message.

  3. 3

    Your Mail Profile is Not a Backup

    Mozilla states that a profile stored apart from the program is not a backup and recommends frequent backups. EML files in a folder you choose give you a second copy that other mail programs read.

Prepare Before You Export MBOX Files

Six checks before the first job. Tick them off, then open the software.

  1. Keep a backup of your MBOX files in another folder. Mozilla recommends frequent backups of mail data.
  2. Install Microsoft .NET Framework 4.5 or above. Allow 100 MB free disk space and 2 GB RAM on the Windows machine.
  3. Open the software with Run as Administrator on Windows 10, 8.1, 8, 7 or Vista.
  4. Locate the MBOX files or the mail client profile. Default Profile Configured fetches files from a configured client. Browsing covers the rest.
  5. Choose a destination folder with free space for the EML files and decide the naming pattern before you export.
  6. Try the free demo on your MBOX files before buying. Download the MBOX to EML Converter Tool demo and convert 25 items from every folder.

Numbers here follow the Specifications table below. The backup line follows the Mozilla page linked in the Sources.

I had to export quite a large number of MBOX files in limited time. That's when this tool came to rescue because it helped me to convert multiple files in bulk within a short period of time. Highly impressed by its working.

Nickel Thomas, Russia

I was in need of a software that would help me to convert all of my MBOX files along with their large sized attachments. I was quite sceptical regarding privacy breach but this tool helped me complete my task with high accuracy. This tool is totally reliable. Thanks for this amazing product.
