Many users don’t realize how simple it is to export and back up their emails. This guide will show you exactly how to export emails from Outlook across different versions and platforms. You’ll learn which format to choose, step-by-step export instructions, and best practices for managing your email archives.

Whether you need to clean up your inbox, preserve important messages, or move your data to a new system, this guide has you covered. Let’s start protecting your valuable communications.

Why You Should Regularly Export Emails from Outlook

Regular email exports offer multiple benefits. They create a safety net for your important communications. They also help declutter your primary inbox for better performance.

Here are the key reasons to export your Outlook emails regularly:

• Data protection and recovery – Safeguard against accidental deletions, account lockouts, or system failures
• Organization and decluttering – Archive old emails while keeping them accessible when needed
• Compliance and record-keeping – Maintain business records for legal requirements or company policies
• System transitions – Easily migrate emails when changing computers, email platforms, or employers
• Performance improvement – Reduce the size of your active mailbox for faster Outlook performance

Many businesses rely on Outlook for their daily operations. This is especially true in corporate environments where Outlook is preferred for its calendar integration and productivity tools. (Source: Clean Email)

Setting up a regular export schedule ensures you never lose vital information. Think of it as an insurance policy for your professional communications.

Understanding Outlook Export File Formats

Before exporting, you need to understand the available file formats. Each format serves different purposes and has unique capabilities. Your choice depends on what you plan to do with the exported data.

PST Files: The Standard Outlook Format

PST (Personal Storage Table) files are Outlook’s native format. They provide the most complete export option. These files store emails, contacts, calendar items, tasks, and notes in a single container.

PST files maintain all message formatting and attachments. They allow for easy reimporting into Outlook later. Most importantly, they preserve the folder structure of your mailbox.

However, PST files have limitations. They work primarily with Microsoft products. Large PST files (over 2GB) may experience performance issues. Also, they can become corrupted if not properly managed.

Use PST exports when:

• You need a complete backup of your Outlook data
• You plan to restore the emails to Outlook later
• You want to preserve all metadata and attachments
• You need to maintain your folder organization

Other Export Formats (CSV, HTML, MSG)

While PST files work best for complete backups, other formats serve specialized needs:

CSV (Comma Separated Values) exports work well for contact information. They create simple text files that many programs can read. However, they don’t store email content, attachments, or formatting.

HTML exports preserve the visual appearance of emails. They create web pages that any browser can display. This format works well for archiving newsletters or visually rich emails. The downside is that each email becomes a separate file.

MSG files store individual emails in Outlook’s message format. They maintain formatting and attachments for single messages. This format helps when sharing specific emails with others.

Let’s compare these formats to help you choose:

Understanding these formats helps you make the right choice for your specific needs. For most users, PST files provide the most comprehensive backup option.

Step-by-Step Guide to Export Emails in Outlook Desktop

Exporting emails from Outlook’s desktop application offers the most options. The process varies slightly depending on your version, but the core steps remain similar. Let’s walk through them.

Exporting to PST (Outlook Data File)

Follow these steps to create a complete backup of your Outlook emails:

1. Open Outlook and click on the File tab in the top-left corner
2. Select Open & Export (in some versions, look for Import/Export)
3. Click Import/Export to open the wizard
4. Select Export to a file and click Next
5. Choose Outlook Data File (.pst) and click Next
6. Select the folder(s) you want to export (select your email address to export everything)
7. Check Include subfolders to export all nested folders
8. Click Next to continue
9. Choose a location and filename for your PST file
10. Set options for duplicate items (we recommend Replace duplicates with items exported)
11. Click Finish to start the export
12. If you want to password-protect the file, enter a password when prompted (optional)

The export time depends on the size of your mailbox. Large mailboxes with many attachments may take several minutes or even hours to complete. Be patient and don’t close Outlook during the export.

Exporting to Other Formats

To export emails in alternative formats, the process starts similarly but diverges after the initial steps.

For CSV exports (useful for contacts):

1. Follow steps 1-3 above
2. Select Export to a file and click Next
3. Choose Comma Separated Values and click Next
4. Select the folder containing the items you want to export
5. Choose a location and filename for your CSV file
6. Click Next and then Finish

For HTML exports:

1. The direct HTML export option is limited in newer Outlook versions
2. Instead, create a folder on your desktop
3. Select the emails you want to export
4. Drag them to the folder while holding the Shift key
5. This saves each email as an individual HTML file

The export process appears straightforward. However, many users encounter issues with large exports or specialized needs. The next sections address these scenarios.

How to Export Emails in Outlook for the Web (Outlook.com)

Outlook’s web version offers fewer export options than the desktop application. However, you can still save your important emails. The process works for Outlook.com, Office 365 webmail, and Exchange Online.

To export emails from Outlook web:

1. Sign in to your Outlook account online
2. Click the Settings gear icon in the top-right corner
3. Select View all Outlook settings at the bottom
4. Go to General > Export email
5. Choose the format (usually .eml format for emails)
6. Click Export to begin the download

The web version has important limitations. It doesn’t export to PST format directly. You can only export limited numbers of emails at once. The original folder structure may not be preserved.

A better approach for web users who need comprehensive backups is to:

1. Set up the Outlook desktop application
2. Connect your web-based account
3. Use the desktop export options described earlier

This method gives you full export capabilities even for web-based Outlook accounts. The desktop application handles most of the complexities for you.

Let’s compare the capabilities across different Outlook platforms:

As shown above, desktop Outlook provides the most comprehensive export options. Web users with significant export needs should consider installing the desktop application.

Exporting Emails from Outlook Mobile App

The Outlook mobile app doesn’t offer direct export functionality. This limitation affects both iOS and Android versions. However, you can still preserve important emails from your mobile device.

For individual emails, you can:

1. Open the email you want to save
2. Tap the three-dot menu (…)
3. Select Forward or Share
4. Choose to save as a PDF or forward to yourself
5. Use cloud storage apps like Google Drive or Dropbox to save the PDF

For comprehensive mobile backups, use this workaround:

1. Ensure your mobile Outlook is synced with your account
2. Access the same account on desktop Outlook or Outlook web
3. Perform the export from the desktop or web interface
4. This captures all emails, including those you’ve viewed on mobile

Microsoft continues to evolve its Outlook options. Currently, Microsoft 365 serves 3.7 million companies globally, including 1 million in the U.S. (Source: Expert Insights) This large user base drives ongoing improvements to export capabilities.

The mobile limitations underscore the importance of having desktop access to your Outlook account for complete backup solutions.

Automating Outlook Email Exports

Manual exports work for occasional backups. For regular archiving, automation saves time and ensures consistency. Outlook offers several approaches to automate your export process.

The simplest method uses Outlook’s built-in Rules:

1. Create a rule to move emails to a designated folder after a certain period
2. Regularly export just that folder using the manual process
3. This creates a semi-automated archiving system

For full automation, consider these options:

Power Automate (formerly Microsoft Flow) can create workflows that:

• Export emails on a schedule
• Save them to SharePoint, OneDrive, or other storage
• Send notifications when exports complete

Third-party tools like SysTools Outlook Backup or CodeTwo Backup offer:

• Scheduled PST exports
• Incremental backups (only new emails)
• Compression and encryption options
• Multiple destination support

When setting up automated exports, consider:

• Storage space requirements
• Network bandwidth during export
• Security of exported files
• Naming conventions for multiple exports

Automation works particularly well for businesses. With 28.75 million monthly active users and 958,000 daily active users on Microsoft 365 platforms, many organizations need systematic approaches to email archiving. (Source: Expert Insights)

Regular automated exports reduce the risk of data loss and simplify compliance with record-keeping requirements.

Best Practices for Managing Exported Outlook Emails

Creating exports solves only half the challenge. Managing those exports effectively ensures you can find and use the information when needed.

Organizing Your Email Exports

A consistent organization system makes all the difference. Start with these naming conventions for your export files:

• Date-based names – Include YYYY-MM-DD format for easy chronological sorting
• Content descriptors – Add brief labels indicating what the export contains
• Version indicators – Use incremental numbers for multiple exports of the same content

For example: “2024-05-15_ClientEmails_v2.pst” clearly indicates when the export was created, what it contains, and that it’s the second version.

Create a logical folder structure for storing exports:

• Primary folders by year or project
• Subfolders by month or category
• Separate locations for different email accounts

Consider adding metadata to your files:

• Use file properties to add tags and categories
• Create a simple spreadsheet index of your exports
• Note the email date ranges in each file

Well-organized exports save time when you need to retrieve specific information. They also prevent duplicate exports from consuming unnecessary storage.

Storing and Securing Your Email Exports

Email exports often contain sensitive information. Proper storage and security are essential. Consider these options for storing your exports:

Regardless of storage location, implement these security measures:

1. Password-protect PST files during export
2. Encrypt sensitive exports using tools like VeraCrypt or BitLocker
3. Control access with proper permissions and user accounts
4. Create backup copies of critical archives
5. Test restore procedures periodically

Remember that the most organized export is useless if you can’t access it when needed. Balance security with accessibility based on your specific needs.

Troubleshooting Common Outlook Export Problems

Even with careful planning, export issues can arise. Knowing how to solve these common problems saves time and frustration.

Size Limitations and Solutions

Outlook imposes size limitations on PST files. These limits vary by version:

When facing size issues:

• Export to multiple smaller PST files by folder or date range
• Remove large attachments before exporting
• Use compression tools on the exported PST
• Consider archive solutions designed for large mailboxes

Error Messages and Fixes

Here are solutions for common export errors:

If you encounter persistent errors:

1. Update Outlook to the latest version
2. Repair your Office installation
3. Check for conflicting add-ins
4. Try the export in Safe Mode (hold Ctrl while launching Outlook)

For corrupted exports, use Microsoft’s Inbox Repair Tool (scanpst.exe) to attempt recovery. This utility is installed with Outlook and can fix minor PST file issues.
