Export Outlook Emails to a PST File Using the Import/Export Wizard

The standard and most reliable method to back up Outlook emails is by using the built-in Export feature in the classic Outlook desktop client.

Microsoft Outlook includes a built-in wizard specifically designed to help you export your emails, contacts, and calendar data into a standalone Data File (.pst). This method allows you to select specific folders or your entire mailbox to ensure important data is saved locally.

Open the Import/Export Wizard

Launch your classic Microsoft Outlook application. Click on the 'File' tab in the top-left corner, click on 'Open & Export' in the left menu, and then click the 'Import/Export' button.

Choose Export Action

In the Import and Export Wizard dialog box, select 'Export to a file' from the list of actions and click 'Next'.

Select the File Type

Choose 'Outlook Data File (.pst)' as the type of file you wish to create, then click 'Next'.

Select Folders to Back Up

Select the specific mail folder you want to back up. To back up your entire mailbox, click on your email address at the top of the list and check the box that says 'Include subfolders'. Click 'Next'.

Save the Backup File

Click 'Browse' to choose a safe destination on your computer or an external drive, and give your backup file a name. Choose your preferred option for handling duplicate items, then click 'Finish'.

Set an Optional Password

A prompt will appear asking if you want to add a password for extra security. You can enter a password to protect the file or leave both fields blank and click 'OK' to finish generating the PST backup.

Frequently Asked Questions

Can I open a PST file without Microsoft Outlook?

Natively, PST files require Microsoft Outlook to be opened and viewed. However, you can use third-party PST viewer tools to read the contents of the file if you do not have Outlook installed on your current computer.

How do I restore emails from my PST backup?

To restore emails, open Outlook and navigate to File > Open & Export > Import/Export. Select 'Import from another program or file', choose 'Outlook Data File (.pst)', browse for your saved backup file, and follow the prompts to import the data back into your active mailbox.

Why is the Import/Export option greyed out in Outlook?

This typically happens if you are using the 'New Outlook' for Windows, which currently has limited support for PST exports, or if your organization's IT policy has explicitly restricted the export feature. Switching back to the classic Outlook view often restores the Import/Export functionality.

Does a PST backup include my contacts and calendar events?

Yes, if you select your entire mailbox (by clicking your email address at the root level) and check the 'Include subfolders' option during the export process, Outlook will back up your emails, contacts, calendar events, and tasks into the single PST file.
