MailDex Windows software for indexing email and file attachments.

Searching through large quantities of .EML formatted email files is a daunting task. MailDex software for Windows by Encryptomatic LLC makes the job easy. MailDex will build an index you can search. The index will contain the body text, and header information. You can even optionally choose to index files attached to the emails.

Download the MailDex free trial and follow along.

MailDex’s interface is project driven. That just means that you can have multiple MailDex indexing projects. The benefit of this is that you can create separate silo’s of email data. These silos are not mingled. For example, if you were working at a law firm and you were working on multiple cases, you could create a separate project for each case. Later, you can permanently delete an email indexing project without impacting the other cases.

Step one is to create an email project in Maildex.

This is the MailDex software full user interface. It has selectable options on the top,  indexing projects on the left. On the right it reads "Getting Started with Maildex". Below that are icons reading: User Guide, Support, Email, Quick Start Videos, Home Page.
In the lower right segment is a list of emails that can be selected and viewed.

From the left side of the MailDex main screen, click on “New” to create a new project, and give it a name. After clicking OK, your new project will appear on the left side.

If you hover over the project name, MailDex will show you the status. Of course, we haven’t added any emails yet, so the status is empty.

The next step is to add emails to your new project. You can add one eml file, select multiple eml files, or even better, just add an entire Windows folder of .eml email files. There is no limit to the number of eml emails MailDex can index.

MailDex supports more than just .eml emails, though. It can also index MBOX, EMLx, PST, OST, and MSG emails as well.

After adding emails to your project, MailDex automatically indexes them. After a short indexing period (indexing file attachments will take longer), you are ready to search your new email data base.

MailDex supports simple email string search and advanced search.

From the MailDex search tab, you can do a “quick search” to find all emails containing a specific string. An advanced search will allow you to set specific search conditions, such as searching between dates, or searching only emails sent between specific email addresses.

Converting Outlook .PST Emails to MBOX Format with Eml Viewer Pro

Are you leaving Microsoft Outlook for another email client?  Most non-Outlook clients are unable to import Outlook .pst/.ost files because the format is proprietary to Microsoft.  A workaround is to convert your Outlook .pst emails into an open email format called MBOX, or MBX.

For converting email files to different formats, EmlViewer Pro by Encryptomatic LLC (also known as PstViewer Pro) is a helpful and affordable Windows software tool.  EmlViewer Pro can read in files such as Outlook .pst, .ost, .eml, and .msg, then output the emails to different target formats, including MBOX, CSV, HTML, PDF, image files like PNG, GIF, and more.

Today’s lesson is focused on showing you how to use EmlViewer Pro to convert Outlook .pst files directly to .mbox.  MBOX is an open format that is supported by most email clients (other than Outlook) including Mozilla Thunderbird.
The first step is to open EmlViewer Pro and choose your .pst file.  Each email in the Pst file will be displayed on a line in the mail list.
Next, click on EmlViewer Pro’s “Export” menu tab, then select “MBOX from the drop down list. The partial screen shot below shows the Export menu with MBOX selected.

Next, select the emails you want to add to the MBOX file from EmlViewer Pro’s mail list. To select all emails, type CTRL-A.  Selected emails are highlighted in blue.  You can select all emails, a range of emails, or just certain emails.
To begin the export process, click the yellow “Export” button.
EmlViewer Pro will display a status window that shows the progress of your conversion.
