Accurate Email Data Acquisition

Aid4Mail easily handles very large messages and attachments, and huge mailbox files. It often succeeds in extracting mail from corrupt mailboxes and fixing malformed emails. Aid4Mail can also restore deleted and unpurged emails from many mailbox formats and IMAP mail accounts.

Aid4Mail is one of the most accurate tools on the market when it comes to rebuilding mail. When programs like Outlook and Eudora receive an email, they alter and split it prior to saving in the mail store. Traditional forensics tools are often incapable of correctly putting the pieces back together. As a result, collected data is incomplete and searches miss relevant chunks of data.

Aid4Mail can rebuild emails, producing a format that is as faithful as possible with the original RFC message. Source metadata like SMTP header fields are recovered, status information and dates restored, and attachments and embedded contents copied back into the email.

Output Formats for Delivering and Filing Email Data

Aid4Mail offers several export options to ease the delivery and filing of collected email data. It can convert messages to PDF or HTML to facilitate file sharing with the court and legal teams. Aid4Mail can also create PDF/A-1a (Level A Conformance) files which are being adopted by federal courts in the U.S. as the standard format for electronic filing (CM/ECF systems).

If you need to analyze or process mail further using other tools, Aid4Mail can export messages to standard Outlook PST files, mbox (formatted for Windows, Mac, or UNIX/Linux), individual EML message files, CSV (supported by Microsoft Excel and most databases), XML, and more. Custom output formats can also be created with Aid4Mail's powerful scripting capabilities.

Command-Line Option

Aid4Mail Console is a command-line edition that can be used to automate examination tasks and batch process email files and accounts. Unlike the wizard edition of Aid4Mail, the console edition can process multiple PST files unattended.

Aid4Mail Console is included in the price of Aid4Mail eDiscovery Service and is available as a bundled option with Aid4Mail Forensic.

Please check if your computer meets the System Requirements before buying!

  • Operating System : Aid4Mail runs under Windows 8, 7, Vista, XP, 2000, Server 2012, 2008 and 2003 or Linux in conjunction with Wine. Both Windows 32-bit and 64-bit are supported.
    Windows NT4 / ME / 98 / 95 should work but are not officially supported.
  • Internet : Online license activation, validation, and re-activation require an internet connection (offline activation option available with Aid4Mail eDiscovery editions).
  • Hardware Requirements : 64 MB of RAM, 12 MB disk space. Pentium (or compatible) processor.


  • Aid4Mail currently does not support the 64-bit versions of Office Outlook 2010 or 2013. But Windows 64-bit with Outlook 32-bit is fine.
  • Office Outlook (32-bit version) must be installed to process mail to or from Outlook/Exchange profiles, *.msg and *.pst files.
    If you don't have Outlook, you can use Microsoft's free 60 day trial of Office Outlook for Windows. Alternatively you can use their free standalone version of MAPI but note that it doesn't support Unicode PST files (which may be used in Outlook 2003 and later versions).
  • Aid4Mail may not be compatible with Click-to-Run installations of Outlook 2010; you will need to re-install Outlook 2010 using another method following Microsoft's instructions. This is not the case for Outlook 2013 which works fine with Aid4Mail 3.
  • If you have Outlook 98/2000 then it should be installed in Corporate/WorkGroup mode in order to process PST and MSG files. If it is installed in Internet Mail Only (IMO) mode, then only the default MAPI profile can be processed.
  • There may be compatibility issues with Outlook 97.
  • PST files from Outlook 2001 for Mac are supported, but not those from Outlook 8.x for Mac. Outlook 2011 for Mac can import PST files created by Aid4Mail.
  • Microsoft Exchange can either be processed through an Outlook/MAPI mail profile, or through the IMAP protocol in which case the Exchange server needs to be set up for IMAP access (see instructions).
