How to Convert Outlook PST to MSG in 2025: A Quick Tutorial

Suppose a user has a PST file containing large data such as emails, attachments, and more. However, they need some of the emails for sharing outside of Microsoft Outlook. This is where MSG files come in as a solution. MSG files can be easily shared and managed. In this post, we will explore the various methods for converting PST to MSG. We will discuss both a complex manual method and an efficient solution using the Cigati PST Converter Tool. But before diving into the conversion methods, let’s first understand the basics of PST and MSG files.

Understanding MSG and PST Files

MSG Files: MSG files (with the .msg extension) store individual Outlook emails, including the email body, sender/recipient information, attachments, and links. These files can only be opened with Outlook or compatible software.

PST Files: PST files (Personal Storage Tables) store your Outlook mailbox data, including emails, folders, contacts, calendars, and more. They are commonly used for archiving emails, organizing them by year, or sharing in batches. You can have multiple PST files open alongside your main inbox, storing them either locally or in the cloud. While PST metadata might change when moved, the actual email data remains intact.

After understanding the basic differences between MSG and PST files, let’s walk through the possible ways to convert a PST file to MSG.

Best 2 Approaches to Convert PST to MSG Files

In this section, we’ll explore two methods for converting PST files to MSG, ensuring all attachments and other details are preserved. The first method is a manual process that requires technical expertise, while the second approach utilizes an automatic, professional tool that is easy to use.

#1: Manual PST to MSG Conversion Using Outlook

Microsoft Outlook does not offer a direct export function for converting PST files to MSG format. However, you can still convert PST to MSG manually with a few simple steps:

• Open Outlook and navigate to your Inbox.
• Select an email you want to convert, drag it from the Outlook app, and drop the file into an Explorer folder or directly onto your desktop.
• Repeat the process for other emails you wish to convert.
• If necessary, zip the files using any third-party compression tool. If the files are already saved, move them to a folder and zip them.
• Compose a new email and attach the zipped MSG files.

Please note that this method only converts the selected emails from the PST file into MSG format. It doesn’t convert the entire PST file to MSG.

This drag-and-drop method is ideal for converting a few emails, but it is not practical for large batches of emails. It can be time-consuming, and finding specific emails may be challenging. For large-scale conversions, using a PST to MSG converter tool would be more efficient.
