Open Outlook Data File

If you’ve ever come across an old Outlook backup and didn’t know how to access it, you’re not alone. Sometimes the .pst file holds important old messages, calendars, and contacts you want to see again. This article shows how you can open Outlook Data File easily using a standalone viewer without installing Outlook itself. The MSOutlookHelp PST File Viewer lets you view all mailbox items including emails, contacts, calendars, tasks, and notes. It works with both old and new PST formats, so no matter where the file came from, you’re covered. It also supports very large PST files, so you won’t run into size limits.
