To begin with Windows Live Mail forensics and its file format EML file forensics, we need to first understand how actually Windows Live Mail stores emails in Windows OS.

Windows Live Mail (a component of the Windows Essentials Suite) is one of the most renowned freeware email client application with more than 280 million+ active accounts. WLM (Windows Live Mail) efficiently manages multiple email accounts, calendars, contacts, and other data items. Also, Windows Live Mail supports Post Office Protocol (POP3) and IMAP (Internet Message Access Protocol) as an incoming server and Simple Mail Transfer Protocol (SMTP) as the outgoing server.

File Formats & Locations of  WLM Data Files

In Windows Vista OS, the Microsoft Outlook Express email client became history. Windows Live Mail enters the game. It’s inbuilt in most PCs working under Windows 7, at location “C:\Program Files\Windows Mail”. All email messages in Windows Live Mail are stored as “.eml files”, along with folder tree information.

It also contains the additional information that Windows Live Mail requires to display email data. One needs to apply the following options in order to view the hidden folders and file extensions:

  • Control Panel > Folder Options > View > Show hidden files and folders
  • Control Panel > Folder Options > View > Hide extensions for known file types (uncheck it)

Hide extensions: Windows Live Mail Forensics

Default Location of Windows Live Mail in different Windows OS Versions are as follows:

Window XP: –

C:\Users\[UserName]\AppData\Local\Microsoft\Windows Live Mail

Vista or Windows 7: –

C:\Users\[UserName]\AppData\Local\Microsoft\Windows Live Mail

Windows 8: –

C:\Users\[UserName]\AppData\Local\Microsoft\Windows Live Mail

From the above description, investigators can easily find the location of the .eml file in different operating systems. However, from an investigative standpoint, technocrats must know that in Windows Live Mail forensics, the contact database is stored in contact.edb file.

Modes of Operation for Contact Database in Windows Live Mail Forensics

Windows Live Mail provides two modes of operation for contact database: –

  • Default (Offline) mode – No sign in to Live ID
  • Live ID (Online) mode – Live ID Sign in to Windows Live

Now, users can operate Windows Live Mail in one mode at a time. Contacts are unique for each mode when users view them in WLM.

Contact Database File in WLM

  • Windows Live Mail stores all of its Contact databases in a single file called “contacts.edb”.
  • Each mode in WLM should have a unique “contacts.edb” file (same name, different location).
  • Each Live ID used in Live ID (Online) mode must have a unique “contacts.edb” file.
  • The contacts.edb file for Default (Offline) mode is stored in a hidden sub-folder called DBStore. To view the DBStore folder, users have to configure the Windows Explorer to “Show hidden files/folders and protected operating system files”.

The Location of DBStore Folder

WLM 2011 (Pre QFE3 Version) – Windows 7 or Vista

C:\Users\Windows\Username\AppData\Local\Microsoft\Windows\Live\Contacts\Default\15.4\DBStore

WLM 2011 (QFE3 Version) – Windows 7 or Vista

C:\Users\Windows\Username\AppData\Local\Microsoft\Windows\Live\Contacts\Default\15.5\DBStore

Note: – The Default DBStore folder is a hidden folder of the “15.5” folder.

The Location of DBStore folder in Live ID (Offline) Mode

WLM 2011 (Pre QFE3 Version) – Windows 7 or Vista

C:\Users\(username)\AppData\Local\Microsoft\Windows Live\Contacts\(Live ID)\15.4\DBStore
C:\Users\(username)\AppData\Local\Microsoft\Windows Live\Contacts\(Live ID)\15.5\DBStore

Windows Live Mail Forensics to Retrieve Corrupted or Deleted EML Files

Nowadays instant messengers, social networking sites, emails are the major carrier of information. It is mostly used by corporate for professional communication purposes. Thus, the elimination of such information accidentally or otherwise, may cause inconvenience to the users. Finally, to balance such catastrophic situations, Windows Live Mail comes with a “Deleted Items” folder.

This folder is available to store the items deleted from any mail folder of the client. However, cases involving hard deletion of emails are not handled well by the client. Nevertheless, erasing or deleting email messages permanently does not mean that it’s gone forever, it can still be extracted forensically.

Forensic tracing of the email is used for retrieving information from mailbox files for analysis purposes. In order to do the same, we must first be aware of the file extension of emails and technicalities related to it. In the case of Windows Live Mail forensics, the file extension of emails is .eml and further information can be examined using forensic techniques.
