How To Export All Outlook Emails : Archiving All Emails To Pst File

by

To back up all your Outlook emails, you can use the built-in export feature to create a PST file of your entire mailbox. This guide will show you exactly how to export all Outlook emails, whether you’re using Outlook 2016, 2019, 2021, or Microsoft 365. We’ll cover multiple methods, including the classic export wizard, drag-and-drop tricks, and third-party tools for tricky situations.

How To Export All Outlook Emails

Exporting your Outlook emails is easier than you think. Microsoft built a dedicated tool right into the program. It creates a single file that holds every email, calendar event, contact, and task. This file is called a PST (Personal Storage Table).

Before you start, make sure you know where you want to save the file. A external hard drive or cloud folder works best. Also, close other programs to avoid conflicts during the export.

Method 1: Using The Built-In Export Feature

This is the most reliable method. It works for almost all Outlook versions. Follow these steps carefully.

  1. Open Outlook. Go to the File tab in the top-left corner.
  2. Click Open & Export. Then select Import/Export.
  3. In the wizard, choose Export to a file. Click Next.
  4. Select Outlook Data File (.pst). Click Next.
  5. Now you see your mailbox folders. Check the box next to your email address (the top-level folder). This selects everything.
  6. Check the box that says Include subfolders. This ensures all nested folders come along.
  7. Click Next. Choose a save location. Give your file a name like “Backup_2024.pst”.
  8. You can set a password for the PST file. This is optional but adds security.
  9. Click Finish. The export starts. It might take a while if you have many emails.

Once done, you have a complete PST file. You can import it later into any Outlook installation. This method is perfect for a full backup.

Method 2: Exporting From Outlook 365 Or Web Version

If you use Outlook 365 (the subscription version), the process is slightly different. Microsoft sometimes hides the export option. Here is how to find it.

  1. Open Outlook 365. Go to File > Open & Export.
  2. If you don’t see Import/Export, look for Manage or Export options.
  3. In some versions, you need to click Account Settings first, then find the export tool.
  4. Alternatively, use the Export button directly from the ribbon under File > Info.
  5. Follow the same steps as Method 1 once the wizard opens.

For Outlook on the web (OWA), you cannot export directly to PST. Instead, you can download a copy of your mailbox using the Export mailbox option in the admin center. This is more advanced and usually requires IT help.

Method 3: Drag And Drop To Export Individual Emails

This method works if you only need a few emails, not the whole mailbox. It is fast and simple. However, it does not create a single PST file.

  1. Open Outlook. Select the emails you want to export.
  2. Drag them to a folder on your desktop or in File Explorer.
  3. Outlook saves them as .msg files. Each email becomes a separate file.
  4. You can also drag entire folders to export many emails at once.

This is great for sharing specific emails or archiving a few conversations. But for a full backup, stick with the PST method.

Method 4: Using Third-Party Tools

Sometimes the built-in tool fails. Maybe your PST file is too large, or Outlook crashes during export. In those cases, third-party tools help. They are often faster and more reliable.

Popular tools include Stellar Converter for OST, SysTools Outlook Export, and Kernel Outlook PST Repair. These tools can export emails to PST, EML, MSG, or even PDF formats. They also handle corrupted files.

Be careful when choosing a tool. Read reviews and check if it supports your Outlook version. Many offer free trials so you can test before buying.

Step-By-Step For A Third-Party Tool

  1. Download and install the tool. Open it.
  2. Select your Outlook profile or PST file.
  3. Choose the export format (PST is best for backup).
  4. Select the folders you want to export.
  5. Click Export. The tool processes faster than Outlook’s built-in tool.
  6. Save the file to your chosen location.

Third-party tools are especially useful if you have a large mailbox (over 50 GB). They handle big files without crashing.

Preparing For The Export

Before you start the export, take a few minutes to prepare. This saves time and prevents errors.

  • Close all other programs. Outlook needs full system resources.
  • Make sure you have enough disk space. A full mailbox can be 10-50 GB or more.
  • Check your Outlook version. Go to File > Office Account > About Outlook.
  • If you use Exchange or Office 365, check with your IT department. Some policies block exports.
  • Clean up your mailbox first. Delete junk and old emails to reduce file size.

Preparation makes the export smoother. It also ensures you get a clean backup file.

Common Export Issues And Fixes

Even with the best preparation, problems can happen. Here are common issues and how to fix them.

Export Stops Or Freezes

This often happens with large mailboxes. Try these fixes:

  • Restart Outlook and try again.
  • Export smaller folders one at a time.
  • Use a third-party tool for large files.
  • Disable add-ins that might interfere.

PST File Too Large

Outlook has a PST file size limit. For Outlook 2010 and later, the limit is 50 GB for Unicode PST files. If your mailbox is bigger, split the export.

  • Export folders separately (Inbox, Sent Items, etc.).
  • Use a third-party tool that can split files.
  • Archive older emails first to reduce size.

Password Protected PST

If you set a password, do not forget it. Without the password, you cannot open the PST file. Write it down or use a password manager.

Missing Emails After Import

Sometimes emails appear missing after import. This usually happens if you did not select the top-level folder. Always check Include subfolders.

Also, check the import settings. Make sure you are importing into the correct folder.

Alternative Export Methods

Besides PST, there are other ways to export Outlook emails. Each has its own use case.

Export To CSV Or Excel

This exports only email metadata (subject, date, sender, etc.), not the full content. Useful for creating lists or reports.

  1. Go to File > Open & Export > Import/Export.
  2. Choose Export to a file.
  3. Select Comma Separated Values.
  4. Choose the folder to export.
  5. Save the CSV file.

Export To PDF

You can print emails to PDF. This preserves the formatting. But it is slow for many emails.

  1. Open an email. Click File > Print.
  2. Choose Microsoft Print to PDF as the printer.
  3. Save the PDF file.

For multiple emails, use a third-party tool that batch converts to PDF.

Export Using PowerShell

Advanced users can use PowerShell scripts to export emails. This is common in corporate environments. It requires technical knowledge.

Here is a basic script example:

Get-Mailbox -Identity "user@domain.com" | New-MailboxExportRequest -FilePath "\\server\share\backup.pst"

This works only with Exchange Online or on-premises Exchange. Not for standalone Outlook.

How To Import Your Exported PST File

After you export, you might need to import the PST file into another Outlook installation. Here is how.

  1. Open Outlook. Go to File > Open & Export > Import/Export.
  2. Choose Import from another program or file.
  3. Select Outlook Data File (.pst).
  4. Browse to your PST file. Choose how to handle duplicates.
  5. Select the folder to import into. Usually, you import into the same folder structure.
  6. Click Finish.

Your emails appear in Outlook. If you imported into a new profile, you might need to set up your email account first.

Best Practices For Email Backup

Exporting once is good. Regular backups are better. Here are some tips.

  • Schedule exports every month or quarter.
  • Store PST files in multiple locations (external drive, cloud).
  • Use a naming convention like “Backup_YYYY_MM.pst”.
  • Test your backup by importing it into a test profile.
  • Consider using a cloud backup service for automatic backups.

Email is critical data. Losing it can be painful. A little planning goes a long way.
