MailDex has an advanced proprietary email rendering engine able to accurately display complex Microsoft Outlook messages, including Rich Text emails with embedded graphics and special formatting such as shapes, SmartArt and embedded charts. Hundreds of non-standard email formatting exceptions have been identified and individually included, enabling MailDex to render emails that other products can't. This means you get highly accurate images when converting email to image documents such as PDF.

Reply and forward to email messages from MailDex using your default Windows email application, such as Thunderbird, Outlook, or any other email client that supports Simple Mapi.

Easy To Use and Unlimited

MailDex is project driven to provide you with good work flow. For example, a law firm performing discovery on multiple cases can establish multiple projects. This simplifies discovery and prevents content mingling.

With MailDex, you can create an unlimited number of projects. Each project can index an unlimited number of emails. Search across one project, or search across all of your projects. Email files within a project may be removed from your MailDex index at any time. Delete any project without affecting any other projects.

Create organized email indexing projects with MailDex.

Begin using MailDex in two simple steps: 1), create a project, 2) add emails to it.

MailDex natively supports indexing of many different types of email content. You can add Outlook .pst, .ost or .mbox email files, or select a Windows folder with .msg or .eml files or a mix of email content. MailDex immediately begins indexing email content after it is added to a project. The status column keeps you informed of the indexing progress.

MailDex is optimized for fast indexing, exceeding 12,000 emails per minute on a modestly resourced computer. When indexing is complete, your searches of email content will return lightening fast results.

Controlled Unclassified Information:

If you work with Controlled Unclassified Information (CUI), MailDex can be set to respect CUI tagged emails during export operations. Activate this feature by selecting the "Exclude CUI" option on the export tab.

MailDex can exclude processing of CUI flagged emails.
