Outlook Pst File Location Windows 11 May 2026

If you use Microsoft Outlook (from Microsoft 365, Office 2019, 2021, or 2024), all your emails, contacts, calendar events, and tasks are likely stored in a single file with a .pst extension (Personal Storage Table).

Once you find it, copy that file to an external hard drive or a safe cloud folder (with Outlook closed) to ensure you never lose a year's worth of emails. Do you use POP3 or IMAP?
