PST file usually stores your entire mailbox, including emails, contacts, calendars, and other items. However, many users prefer converting PST emails into MSG format, especially when they want individual messages instead of a bulky PST file. MSG files are simple, easy to access, and perfect for sharing or storing specific emails. In this blog, you will find every simple and verified step, including the Aryson PST Converter Tool to convert PST to MSG format without any data loss.

Why Do Users Convert PST to MSG?

There are several reasons why users choose MSG over PST. Some of the most common situations include:

  • Easy Sharing: MSG files allow you to share a single email instead of the entire PST file.
  • Better Email Management: You can save important messages separately for future use.
  • Simple Access: MSG files open directly in Outlook with a double-click.
  • Quick Archiving: Storing important conversations becomes easier with individual email files.
  • Selective Access: You get better control as you save only the emails you need.

Because of these advantages, MSG becomes a preferred format when users want flexibility and organized email storage.

Available Methods to Convert PST to MSG

There are two widely used methods:

  1. Manual Method using Microsoft Outlook
  2. Automated Method to Export PST to MSG.

Both methods work, but they suit different types of users. Therefore, you will see each method in detail so you can choose what fits your requirements.

Method 1: Convert PST to MSG Manually Using Outlook 

The manual process works well when you have fewer emails to convert. However, it takes time and requires Outlook on your system. You can follow the steps below.

Step 1: First, Open Your PST File in Outlook

To begin the process, you must load the PST file inside Outlook so you can access all its emails.

  • Open Microsoft Outlook on your system.
  • After that, click on File, which appears in the top-left corner.
  • Next, choose Open & Export, and then select Open Outlook Data File.
  • A new window will appear. Here, browse your system and select the PST file that you want to convert.
  • Finally, click OK.

Once Outlook loads your PST, you will see all the folders—such as Inbox, Sent Items, Drafts—on the left panel. This ensures your PST data is ready for conversion.

Step 2: Next, Select the Emails You Want to Convert

After your PST is visible in Outlook, you must choose the emails that need to be saved as MSG.

  • Open any folder from the PST, like the Inbox or the Sent Items.
  • Then, click on the specific email you want to export.
  • If you want to select multiple emails, you can press Ctrl and click on each email one by one.
  • Or, if you want to select a continuous range of messages, hold Shift and select the first and last email.

This step helps you pick only the important emails instead of converting the entire PST file.

Step 3: Finally, Save the Selected Emails in MSG Format

Once your emails are selected, you can convert them to MSG.

  • Right-click on the chosen email.
  • From the options shown, click Save As.
  • A new window will open. Here, choose MSG – Outlook Message Format from the “Save as Type” dropdown.
  • After that, click Browse to choose the location where you want to save the converted MSG files.
  • Finally, click Save.

Outlook will instantly save the email as an MSG file in the selected folder. If you selected multiple messages, you must repeat this step for each one.

Why the Manual Method Falls Short

Although the manual steps are simple, they have some drawbacks. These limitations become more noticeable when users handle large PST files.

  • It is slow when you have hundreds or thousands of emails.
  • You must save each email manually, which increases your workload.
  • Outlook installation is mandatory to perform the conversion.
  • Bulk conversion is difficult and time-consuming.
  • Any mistake during selection can lead to missing emails.

Because of these restrictions, the manual method is not suitable when speed, accuracy, and efficiency are important.
