Understanding PST and MSG Files

Before discussing the conversion methods, let’s first have a brief understanding of these two formats.

PST (Personal Storage Table): This is Microsoft Outlook’s proprietary format for storing full mailbox data, such as emails, attachments, contacts, calendars, and more.
MSG (Message): MSG Files are single email message files containing the sender, recipient, subject, body, and attachments. MSG files are one individual Outlook item that contains a single email.

To put it simply, a PST file is like a large box that contains all of your Outlook data, and MSG files are like individual envelopes for each of your emails.

Reasons to Convert PST to MSG Files

There are several real-world situations in which users would want to export PST emails to MSG files:

Email Storage: If you want to keep separate MSG files of individual emails that are important to you before you share them or ask someone for advice about how to handle them in the future.
Backup: You could back up essential or important emails and import them later instead of backing up the entire mailbox.
Portability: MSG files can be copied and transferred from machine to machine, and you can open them directly in Outlook.
Recovery: If a PST file becomes corrupt, one of the possible steps to recover messages could be to export the email into MSG format.

If you’re an organization, you may want to consider convert different types of emails for legal purposes, as it is often better when the metadata stays with the message in MSG format versus in PST format.

Alternative Approach to Export PST to MSG Files using Manual Technique

If you have Microsoft Outlook installed, you can manually convert PST files to MSG files with a drag-and-drop method.

Follow the steps below:

Open up Microsoft Outlook on your PC.
If your PST file hasn’t been loaded, import the PST file:
File > Open & Export > Open the Outlook Data File and choose your desired PST.
Select the applicable folder (like Inbox or Sent Items) that has the email messages to be converted.
Create a folder on your computer to save the MSG files.
Drag and drop single email messages from Outlook into that folder.
Outlook will create each email in .msg format automatically.

Disadvantages of the Manual Method

You can only export one email at a time.
Bulk conversion takes time.
There is no filtering or selectivity for conversion.
You must have Outlook on your machine.
If you plan to work with multiple PST files or larger files, it is advisable to use a professional solution.
