PST files are personal folder files in Microsoft Outlook. Outlook personal folders and archive items will be located in files with the extension .pst, and your information will be stored on your computer's local hard drive.

This feature allows you to access previously downloaded or synchronized emails, calendar information, contacts, and tasks without a network connection.
