Whether deleted items can be viewed depends on how they were removed from the PST. If the messages are still retained within the mailbox structure, they may remain accessible for viewing. However, permanently deleted or overwritten data may require a specialized recovery solution rather than a standard viewer. Working with a copy of the original PST is recommended to avoid accidental changes.

Instead of modifying the source file, you can use Aryson PST Viewer to inspect the available mailbox contents. The software allows users to open PST files and browse stored emails, contacts, calendars, and attachments without depending on Microsoft Outlook. This makes it useful for checking whether specific messages or other mailbox information are still present in the PST. To view deleted items from a PST file, load the original file and examine the available folders and messages carefully. If the required items are visible, you can review their contents without altering the source mailbox. When deleted emails are no longer available, however, a dedicated PST recovery tool would be more appropriate for attempting deeper data recovery.
