Jordan Walker Query: I have a collection of EML files that are stored on my computer. Now, how can I import all these EML files into one PST that will be more accessible for me?

Summary: An EML file stores a single email per file, which consumes large storage space in case of multiple emails. Therefore, to save storage space and improve email accessibility, users convert EML files to a PST file. This write-up incorporates two methods to accurately and securely convert EML to PST. The MacSonik EML Converter tool will provide the capability to easily convert EML files in bulk efficiently. Then, a manual approach without using any tool will be described. For professionals, using the tool will be best, and for personal use, users can choose the manual method.

Why do Users Export EML to PST?

There are multiple reasons for users to transfer their EML to PST, such as migration, organization, management, and more. Some of them are described below in detail:

1. If a user is migrating from Thunderbird to Outlook, they need a conversion to access their emails in Outlook.
2. EML files consume large storage space, whereas PST files store multiple emails in the same storage space.
3. In addition, it’s easier to manage one PST file as compared to a hundred or thousands of EML files.

Best of Available Approaches to Convert EML to PST

We’ll explore two user-friendly approaches in this section to help you move EML files into PST format.

1. Manual Method: Utilize Outlook to save EML files as a PST file.
2. Automated Tool: Employing a professional utility with advanced features.

Manually Migrate EML to PST

Therefore, below are the steps for migrating EML files:

3. Now, concurrently open the location where EML files are stored, and select all EML files to be imported.
4. Afterward, drag these EML files and place them into the newly created folder in Outlook.

Step 2: Export the folder we made to convert EML Files to PST

2. Next, opt for the Export to a file feature and click on Next to move forward.

5. Lastly, choose the folder to store the resultant PST file and click Finish to end the process.
