Outlook stores all of its information in PST files, as we all know. The mailbox items, like emails, contacts, calendars, tasks, notes, and journals, are saved in the PST format. There are several situations in which a user would need to Export PST to MSG Files for different reasons. When customers have Microsoft Outlook as their email client and wish to talk about email data with other people, it helps to extract emails from the PST file and change them to MSG. But it can be hard to import a lot of PST files into Outlook so that you can see and access all the data in them.

You've come to the right site if you want to know how to change PST files into MSG files. Let's start with an introduction to PST and MSG to get a better idea of what they are.

What is a PST File and an MSG File?

Emails in MSG files include the sender's and recipient's identification, the date and time the email was sent, the subject, and the whole text of the message. If you save calendar appointments, the MSG file will hold the date, time, and other people who have been invited.

The PST file extension for Outlook, on the other hand, holds all of Outlook's data, such as contacts, addresses, calendar entries, tasks, notes, to-do lists, and more. I'll talk about the different reasons we need to change PST files to MSG files here.

Why You Should Export Outlook to MSG Files

  • There is a danger that the PST data file will be damaged if it is quite large.
  • When you have a lot of Outlook emails, one of the fastest ways to get to your data quickly is to export PST to MSG.
  • If your Outlook PST files are too large, they could make your computer run slowly.
  • The MSG file's original content has been kept. The hierarchical structure might still be where it was.
  • MSG works with both web-based and mobile-based apps. However, PST only works with web-based apps.
  • Simple ASCII or binary text is used to represent MSG files, which include all headers, message systems, connections, and attachments.

There are a lot of reasons to convert PST files to MSG files. Now let's talk about how to fix those problems.

How to Manually Convert Outlook PST to MSG

  1. Open the Microsoft Outlook program on your computer.
  2. Go to the location on your computer where you want to create a new folder.
  3. Open Outlook now, go to the Inbox folder, and choose the email messages you want to save as an MSG file.
  4. After you choose the emails you want to move, drag and drop them into the new folder.
  5. When the process is done, you will be able to see or access your PST data in the MSG file.

It's a manual technique to export a PST file with attachments. But you can only use this way to change limited PST data into MSG.

Disadvantages of the Manual Method

Here are a few important things to remember regarding the manual step: This procedure could be hard to understand for non-technical users when they need to convert a lot of PST data. Converting a PST file to an MSG file doesn't take a lot of time, but the user needs to do the right things in Outlook. When you migrate files by hand, mistakes might happen that can corrupt files or even lose data.

Don't worry; you can also use professional software to export PST to MSG and read MSG files with just one click.

How to Use Expert Solution to Export PST to MSG Files

As I said before, the manual approach has several problems, like not being able to move more than one file at a time. To save time and effort, I told users to look for a professional tool called GainTools PST to MSG Converter that lets them Export PST to MSG Files. Using this third-party software also lets you convert single and multiple Outlook PST to MSG files without losing any data in a way that is easy for users.
