Convert PST to MSG

This tool converts Outlook items from PST data files to MSG format. You can keep the original folder structure. Unlike other formats, PST to MSG conversion preserves all MAPI properties of Outlook items without data loss. It is a convenient format for Outlook import, export and backup.

Outlook Data File (.pst)

An Outlook Data File (.pst) contains all your email messages, calendar, contact, task data and other Outlook items. If you cannot open your Outlook data file, you can extract emails from pst to msg files.

MSG File Format (.msg)

A MSG file (.msg) contains Outlook Item, which is used to represent individual email messages, appointments, contacts, tasks, and so on in the file system. Each MSG file contains all the data for a single Outlook item.

How to convert PST to MSG?

5. Select destination folder and click Ok.
6. Wait for the export to finish and click Ok.

Custom options when saving MSG from PST

The utility provides predefined file naming options for exported MSG files:

• Item Subject
• Incremental Numeric ID
• PR_ENTRYID field

There are three options for which items to save:

• Selected items
• All Items in this folder
• All items in this folder and subfolders

When you select the subfolder processing mode, the utility creates the original Outlook folder structure on your local disk or network share. These folders contain messages, contacts, notes, and all other Outlook items converted to MSG format.

Online services to convert PST to MSG

PST files contain your important and confidential data. When you use an online service to convert email from PST to MSG, all of your sensitive data, including private messages, contacts, tasks and notes, is transferred to someone else's server. The data is processed on an unknown computer and you have no control over it. Only then will you be able to download the resulting MSG files.

Are there any limits when converting from PST to MSG?

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

Bulk PST to MSG conversion

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

pstwalker-cli.exe 
   [filename] 
   [-E:<FileFormatParameter>] 
   [-Name:<NamingStyleParameter>] 
   [-SearchQuery:<String>] 
   [-ExportPath:<DestinationPathParameter>] 
   [-FullScan] 
   [-HardDeleted | -HardDeletedOnly]
   [-Log]

Example

cd "C:\Program Files (x86)\PST Walker\"
$PSTFiles = @("c:\a.pst", "c:\b.pst")
foreach ($PST in $PSTFiles){
   .\pstwalker-cli.exe "$PST" --% -E:msg -SearchQuery:'from:(=bobbymoore@contoso.com OR "bobby moore")'-ExportPath:"D:\PST-Exports\"
}

This example searches c:\a.pst and c:\b.pst 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 .msg files to D:\PST-Exports\.

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.
