In the realm of email management and data migration, converting PST files to EML format is a common challenge faced by many. Whether you're transitioning from Outlook to another email client that supports EML files, or you simply need to extract individual emails for archiving purposes, understanding the process of PST to EML conversion is essential.
The Growing Need for PST to EML Conversion
Microsoft Outlook remains a cornerstone in corporate environments, widely used for its robust email management, calendar integration, and collaboration tools. However, organizations and individuals often find themselves needing to migrate away from Outlook due to cost considerations, platform compatibility, or the adoption of lightweight email clients like Thunderbird or Apple Mail. For instance, startups or remote teams might prioritize cost-effective solutions that integrate seamlessly across multiple operating systems, making EML a preferred format. Similarly, legal and healthcare sectors frequently require archiving emails in universally accessible formats for compliance, where EML's simplicity shines.
Understanding PST and EML Files
Before diving into the conversion process, it's important to understand what PST and EML files are and why you might choose one format over the other.
What is a PST File?
A PST (Personal Storage Table) file is a proprietary data file used by Microsoft Outlook to store email messages, contacts, calendar events, tasks, and more. Due to its complex and monolithic structure, a PST file may become bulky and prone to corruption if not maintained properly.
What is an EML File?
EML (Electronic Mail) files represent individual email messages, including headers, body content, and attachments, in a simple and portable format. EML is compatible with a variety of email clients such as Mozilla Thunderbird, Windows Live Mail, and Apple Mail, making it a preferred choice for data migration, backup, and archival purposes.
By converting PST files to EML, you can break down large, cumbersome files into manageable individual messages. This enhances flexibility, simplifies data sharing, and ensures cross-platform accessibility.
Why convert PST to EML?
Converting PST to EML is not just a technical exercise—it has practical benefits that can significantly enhance your email management strategy. Below are some of the primary reasons to convert your PST files:
Enhanced Compatibility and Flexibility:
EML files are supported by virtually every email client beyond Outlook, including Thunderbird, Apple Mail, and even webmail services like Gmail when using third-party tools. This cross-platform compatibility is invaluable for teams using mixed operating systems (Windows, macOS, Linux) or hybrid workflows. For example, a marketing agency collaborating with freelancers might need to share email campaigns in a format accessible to all, avoiding Outlook dependency.
Simplified Email Archiving and Sharing:
Legal teams often archive correspondence for compliance, and EML's single-file-per-email structure simplifies indexing and retrieval. Instead of sifting through a monolithic PST file, each email is a searchable file. Additionally, sharing individual EML files via services like Dropbox or Google Drive is more efficient than transferring large PST files, which may exceed attachment size limits.
Seamless Migration to Other Email Clients:
Organizations transitioning to cost-effective or cloud-based solutions (e.g., Thunderbird, Zimbra, or ProtonMail) require PST to EML conversion to preserve historical data. Startups scaling rapidly might abandon Outlook due to licensing costs, opting for open-source alternatives where EML ensures data continuity.
Reduced Risk of Data Corruption:
PST files are notorious for corruption, especially when exceeding or improperly closed. Corruption can render years of data inaccessible. EML files, being discrete, minimize this risk—a critical advantage for sectors like finance or healthcare, where data integrity is non-negotiable.
Improved Organization and Searchability:
Many conversion tools maintain the original folder hierarchy during conversion, which not only helps preserve the logical organization of your email data but also facilitates efficient navigation and retrieval of messages, while storing emails individually enables search functions across various email clients to quickly locate specific messages based on sender, subject, or date.
In summary, converting PST to EML offers increased control, improved data portability, and enhanced security. It's a practical solution for both migration and archival purposes.
How to Convert PST to EML?
There are several approaches to converting PST files to EML, each suited to different needs and levels of technical expertise. Below, we outline four distinct methods along with detailed step-by-step instructions.
Important: Before proceeding with any methods for PST to EML conversion, it's crucial to prepare a backup of your PST files. Creating a backup ensures that your original data remains intact and secure, safeguarding against potential data loss or corruption during the conversion process.

Method 1: Convert PST to EML Using Microsoft Outlook and Thunderbird
This manual method leverages Outlook and Thunderbird's interoperability. It's a two-step process that first requires you to import your PST file into Thunderbird, followed by exporting the emails as EML files. This approach is beneficial for users who prefer not to use third-party PST to EML conversion software. To proceed, ensure you have both Microsoft Outlook and Mozilla Thunderbird installed on your computer.
Step 1: Import PST to Thunderbird
- On your Windows machine, navigate to Settings and select Default Programs option.
- Click on Email and choose MS Outlook (Desktop) from the Choose an app list. This step ensures Thunderbird can locate and import the PST file directly from Outlook.
- Launch Thunderbird and click on the menu icon.
- Select Tools > Import option.
- From the Import Tool window, choose Import from Outlook and click on the Continue button.
- Select Mail Messages as an option and click on the Continue button.
- To start the import process, click on the Start Import button.
- Once the process is complete, click on the Finish button.
Step 2: Export EML from Thunderbird
- Navigate through the imported emails in Thunderbird and select the ones you wish to convert to EML. You can select multiple emails by holding the Ctrl key.
- Right-click on the selected emails, then choose the Save As option.
- Select the folder where you want to save the EML files and confirm by clicking on the Select Folder button. Thunderbird will export the selected emails as individual EML files to the specified location.
- After the export process is complete, navigate to the chosen folder to find the EML files. You can now open these files with any compatible email client to verify their integrity and content.
Common Issues & Fixes:
Missing Emails Post-Import:
Sometimes, if Outlook remains open during the import process, it can lock certain files, causing some emails to be skipped or not imported at all. To avoid this, ensure that Outlook is completely closed before starting the import. This precaution allows the conversion tool to access every necessary file without interference, ensuring a complete and accurate transfer of all emails.
Thunderbird Freezes:
When importing very large PST files, Thunderbird can sometimes freeze or become unresponsive due to the overwhelming amount of data being processed at once. A recommended fix is to use Outlook's Archive feature to split the PST file into smaller, more manageable chunks. This approach not only prevents Thunderbird from freezing but also facilitates a smoother and more efficient import process.
This method is particularly useful if you need to convert a manageable volume of data and prefer a hands-on approach without extra software.
Method 2: Convert PST to EML Using Microsoft Outlook and Windows Live Mail
Another effective manual approach involves using Microsoft Outlook to export your emails and Windows Live Mail to convert them into EML files. This method works well for users familiar with both email clients.
Step 1: Export to Microsoft Exchange Server
- Launch Outlook, and click on File > Open > Import.
- The Import and Export Wizard will open. Here, select Export to a file, and click the Next button.
- Choose Microsoft Exchange, and click the Next button.
- Select the folder to export from, and choose a location to save the exported file.
- Click the Finish button to complete the export.
Step 2: Import to Windows Live Mail
- Open Windows Live Mail and click on File > Import > Messages.
- Select Microsoft Exchange as the format, and then click the Next button.
- Navigate to the location of the exported file from Outlook, and click Next to import.
- Once the import is complete, right-click on the email and select Save As to save the email in EML format.
Limitations:
Windows Live Mail's discontinuation means compatibility issues on newer operating system versions. Consider virtual machines for older Windows editions if critical.
This method is especially beneficial for users with smaller PST files or those who already use Windows Live Mail as part of their email management system.
Method 3: Convert PST to EML Using Gmail IMAP
This method involves using Gmail's IMAP feature as a bridge to transfer emails from PST files in Outlook to Thunderbird, facilitating a smooth conversion to EML format. By leveraging Gmail as an intermediary, you can take advantage of its robust IMAP capabilities to manage your email data efficiently across different platforms. This approach is particularly beneficial for those seeking a seamless transition of emails to Thunderbird. Below are the steps to utilize Gmail IMAP for PST to EML conversion.
Step 1: Enable IMAP Protocol in Gmail
- Log into your Gmail account.
- Click on the Gear icon and select See all settings option.

- After verification, click Finish.
Step 4: Migrate Emails from Outlook to Gmail
- In Outlook, under the Gmail mailbox, create a new folder for the emails you wish to migrate.
- Select the Outlook emails you wish to migrate, then press and hold the Ctrl key while dragging the selected emails to the newly created Gmail folder in Outlook.
- Check your Gmail to ensure the emails have appeared in the new folder.
Step 5: Configure Gmail in Thunderbird
- Open Mozilla Thunderbird and navigate to Menu > Account Settings.
- In the left sidebar, select Account Actions > Add Mail Account.
- Provide your Name, Gmail Address, and the app password. Make sure "Remember password" is checked, then click Continue.
- Select IMAP as your configuration and click Done.
- A success message will appear, indicating the successful addition of the Gmail account.
Step 6: Export EML files from Thunderbird
- Navigate to the Gmail mailbox within Thunderbird to locate your migrated emails.
- Select the emails you wish to convert to EML. You can select multiple emails by holding the Ctrl key.
- Right-click on the selected emails and choose Save As to export them as EML files.

Limitation:
Gmail's free 15GB storage limit can quickly be exhausted when migrating large PST files, making it challenging to transfer all your emails at once. To avoid storage issues and ensure a smooth migration, consider breaking the process into smaller, more manageable batches.
Using Gmail IMAP as an intermediary is especially useful for those who have a large volume of emails to migrate and prefer using cloud-based services to facilitate the conversion process.
