Free Methods to Export OST to MSG Files

Outlook doesn’t have a built-in option to export multiple OST emails as MSG files at once. So, you’ll either need to try manual methods or use a professional tool. In this blog, we’ll show you some free ways to export OST to MSG, like drag-and-drop and using Save As. We’ll also look at a trusted tool for those who want a faster and simpler solution.

Key Differences Between OST and MSG Files

After going through the above-mentioned difference table, you can see why people export OST to MSG.

Why Many Users Prefer MSG Over OST

MSG files are often preferred because:

• They save only what you need, there is no bulky mailbox, just one message per file.
• Easy to move, copy, or email to others without exporting entire mailboxes.
• No need to stay connected to a mail server – MSG files open in Outlook directly.
• Great for legal, business, and backup use, where individual email tracking is important.
• Faster to search, sort, and store, especially for organizing project or client-based emails.

How to Export OST to MSG – 3 Methods Explained

There are three free ways you can export Outlook OST emails to MSG format:

1. Using Outlook’s Drag-and-Drop feature
2. Using the Save As option in Outlook
3. Using OST to MSG Converter

Method 01: Drag and Drop Method to Convert OST File to MSG

The Drag and Drop method is a simple manual approach that lets you save individual Outlook emails (from an OST file) as MSG files on your system. It’s a useful trick if you only need to convert a few emails, not the whole mailbox. Here are the steps to export OST to MSG: 

Prerequisites:

• Microsoft Outlook must be installed and configured with the OST file.
• The OST file must be accessible (i.e., not orphaned or disconnected).

Steps to Convert OST to MSG Free

• Open Outlook with the profile that’s linked to your OST file.
• Now, navigate to the folder where your emails are located.
• After that, click on the specific email you want to convert.
• Open the folder on your computer where you want to save the MSG files.
• The next step will be to drag the selected email(s) from Outlook.
• Drop them into the desired location in the File Explorer window.

Each dragged email is automatically saved in MSG format with its subject as the filename.

Limitations of the Drag and Drop Method:

• Works only if Outlook is connected to the original OST.
• Cannot be used for orphaned or corrupted OST files.
• Time-consuming for large numbers of emails.
• Doesn’t support batch export with folders and metadata.

Method 02: Convert OST File into MSG with Save As Option

Another manual way to convert OST file emails into MSG format is by using Outlook’s built-in Save As feature. To perform this method, Microsoft Outlook must be installed on your system. Follow the given steps to export OST to MSG files:

• In the “Save as type” dropdown, select Outlook Message Format – Unicode (*.msg).
  
• To complete the process, choose the folder where you want to save the file and click Save.
  

• The email is now saved as a .msg file at your chosen location.

Limitations of the Save As Method:

•  Cannot be used with orphaned or inaccessible OST files.
