These tools efficiently convert Outlook PST data files to EML format. They provide options to preserve internet transport headers, attachments, and the original folder structure of the PST file. Additionally, they can handle the conversion of corrupted, orphaned, archive, password-protected, and encrypted Outlook Data Files (.pst and .ost).

Converting PST to EML lets you store and back up emails in a convenient format and easily transfer messages between different email clients and systems. EML format stores only email messages, other Outlook items such as contacts, calendar, and tasks can be exported to .eml files as emails.

The data will be processed on an unknown computer, and you will have no control over it until you download the resulting EML files.

Our utility operates strictly on your computer, the information from the PST data file is not uploaded or transferred to any external server. All data processing and conversion take place locally on your computer, ensuring complete control and confidentiality over your data.

Method 3: Using PstScan Pro

The PstScan Pro can bulk convert PST to EML and OST to EML in batch scripts using PowerShell, Task Scheduler and other automation tools. To do this, use the command line options of the product.

Example 1: Searching mailboxes and exporting items to .eml files

PowerShell 
cd "C:\Program Files (x86)\PSTWalker Software\PstScanPro"
$PSTFiles = @("c:\outlook.pst", "c:\outlook.ost")
foreach ($PST in $PSTFiles){
   .\pstscanpro.exe convert eml -f "$PST" -p "D:\PST-Queries" --headers --srcfolders --% -q "from:(=bobbymoore@contoso.com OR ""bobby moore"")"
}

This example searches c:\outlook.pst and c:\outlook.ost mailboxes for items in which the e-mail address equals bobbymoore@contoso.com OR sender name contains bobby moore. The search results are exported as .eml files to D:\PST-Queries directory.

To match an entire phrase, the search string must be enclosed in quotes. All special characters, including quotes, should be escaped using an escape sequence prefixed with a backslash \.

For example:
-q "\"bobby moore\""

Alternatively, for quotes, you may also use double quotes:
-q """bobby moore"""

When running native commands from PowerShell, the arguments are first parsed by PowerShell. Beginning in PowerShell 3.0, you can use the stop-parsing (--%) token to stop PowerShell from interpreting input as PowerShell commands or expressions.

Example 2: Converting all user's .pst files to .eml files

Command Prompt 
cd C:\Program Files (x86)\PSTWalker Software\PstScanPro
pstscanpro.exe convert eml -f c:\users\*.pst -p "D:\EML files" --headers --srcfolders --fullscan --harddel

This example exports both messages and hard deleted messages from all .pst files located in the c:\users folder as .eml files to the D:\EML files directory.

What data is exported?

When converting, the utility saves all available data, such as:

  • message subject
  • send and receive dates
  • sender and recipient addresses
  • message text with HTML and RTF markup
  • attachments and images
  • Internet headers

Are there any limits when converting from PST to EML?

There is no limit on the number and size of the converted PST files and the resulting EML files. You can convert unlimited folders or files as often as you like.
