This article shares the fastest ways to export PST to MSG format via manual methods & dedicated PST to MSG converter. Outlook users, IT admins, & legal teams need PST to MSG conversion. In this blog, users will learn simple methods. Use Outlook, Windows PowerShell, & dedicated desktop-based SHA-secured automatic tool to export PST file to single msg.

Why Do Users Export PST to MSG Files?

Outlook PST stores emails, contacts, calendars, & attachments in a single PST file. Users do PST to MSG conversion because of reasons listed below:

  • When users want to open emails individually, MSG files allow users to open a single email directly without opening a large PST file.
  • To only share specific emails that contain sensitive or secret information with colleagues, senior or closed ones.
  • To keep individual emails accessible even if the original PST file becomes corrupted or inaccessible, users can save important messages as separate MSG files.

So, these were the most common causes of PST to MSG conversion. Instead of dealing with one large PST file containing many Outlook items, users can save, open, & share specific emails into separate MSG files. Now moving on to the next section to check out practically tested techniques.

Convert PST to MSG Outlook in Manual Ways

In this section, you will learn two of the most common ways to convert PST to MSG easily with no data loss. We used Microsoft Outlook to simply save emails from the Mailbox of PST file and Windows PowerShell to extract MSG files from PST file. So, let’s begin with the first free method where you need to use Microsoft Outlook. If you find the first method is not useful, then you can also go with the second, Windows PowerShell method. Lastly, you will also get a bonus method to make your PST to MSG conversion successful completely.

1st Method: Make MSG File with Microsoft Outlook (Classic Outlook)

To do it with use of Microsoft Outlook, you need to follow steps divided below carefully:

Part A: Import PST File into Outlook

  1. Open Microsoft Outlook on your Computer.
  2. Go to File > Click on Open & Export Option > Choose Import/Export.
  3. Then, select “Import from another program or file” > choose “Outlook Data File (.pst).
  4. After that, click on “Browse” button to import stored PST file
  5. Next, hit the Finish button to complete import of PST file in Outlook.
  6. Done, now move to the next part to know the conversion.

Part B: Creation of MSG Files from Imported PST

  1. Now, go to the imported folder inside Outlook.
  2. Choose the “Inbox” or “Sent” folder to open it.
  3. After that, select a single email and double-click to open it.
  4. Go to the file option & click the “Save As” button.

Finally, choose a saving location by browsing on the computer & set it according to storage space. After using this method, you will easily convert PST to MSG files, but you need to repeat these steps of Part B multiple times individually.

2nd Method: PST File Conversion with Use of Windows PowerShell

If you find the above method not useful, then you can go with this method. In this technique, you need to run the given Windows PowerShell script below to export PST to MSG without use of Microsoft Outlook.

  • Run the Windows PowerShell on a Windows computer.
  • After that, simply copy & paste script below into Windows PowerShell

$outlook = New-Object -ComObject Outlook.Application
$namespace = $outlook.GetNamespace(“MAPI”)
$pstPath = “E:\outlook-data\emails.pst”
$namespace.AddStoreEx($pstPath, 1)
Start-Sleep -Seconds 5
$pst = $namespace.Folders | Where-Object { $_.FilePath -eq $pstPath }
if (-not $pst) {
$pst = $namespace.Folders | Select-Object -Last 1
}
$folder = $pst.Folders | Select-Object -First 1
$output = “E:\outlook-data”
if (!(Test-Path $output)) {
New-Item -ItemType Directory -Path $output
}
foreach ($mail in $folder.Items) {
try {
$subject = $mail.Subject
if ([string]::IsNullOrWhiteSpace($subject)) {
$subject = “No_Subject_” + (Get-Random)
}
$subject = $subject -replace ‘[\\/:*?”<>|]’, ‘_’
$filePath = Join-Path $output ($subject + “.msg”)
$mail.SaveAs($filePath, 3)
}
catch {}
}

  • Write-Host “Done”
  • Now, hit the “Enter” button to run this script.
  • After using this PowerShell script, your PST to MSG conversion is successfully done with no use of Outlook.

This script can extract MSG files from PST, to use this script, you need to have working PST files.

Remember: This PowerShell Script works only when you use unprotected PST files. In case you have password-protected PST files and you want to extract MSG files from locked PST files, then you can unlock them with a trustworthy PST password remover tool.

Bonus Technique for PST to MSG Conversion

We assumed you might have learned both manual solutions, & now you can export your PST files into MSG format. But what if you have a new outlook? Don’t worry, you will also get a solution for your New Outlook in the same article. Just follow instructions below while keeping yourself focused on steps. To convert PST to MSG from New Outlook, you must have a subscription-based account of Outlook to import the PST file into.

  1. Open New Outlook on your computer.
  2. Go to the Inbox or Sent folder of your subscription-based account.
  3. Choose any email from inside the selected folder.
  4. Right-click on it & choose the “Save As” option.
  5. Finally, select MSG between EML & MSG, set saving location, & hit Enter to save.
  6. Done, now you have created MSG files from the PST file.

Now, as we all know, if manual methods exist, then their limitations are also. So, we suggest that before using any of these methods also read loopholes of both manual & bonus methods.

Drawbacks of Manual Methods

  • The use of save as method is time-consuming & not useful in case you have more than thousands of emails. Due to this, you might be confused while doing it individually
  • Using save as method doesn’t allow you to filter desired emails by date, sender name, or subject of emails.
  • During the use of save as a method to export PST to MSG, if your system shuts down due to a surge of electricity, your Outlook crashes.
  • Repetition of the same process multiple times carries the risk of duplication and overwriting.
  • Windows PowerShell script is useful in both cases, whether you have Outlook installed or not, and it requires technical scripting knowledge to complete PST to MSG conversion successfully.
  • Given Windows PowerShell script works only on unlocked PST files, if users have a password-protected Outlook PST file, then they need to decrypt first before conversion.
  • If users have large PST files and they are using PowerShell script for conversion, then they might face performance issues during the use of PowerShell.
  • To convert a PST file into MSG from New Outlook, users must have a subscription-based Outlook account to import their PST file into it.
  • The bonus method of New Outlook also has the same limitations that are present in old Outlook Classic.

These were the drawbacks of both manual & bonus methods that you might face while using them.
