Common Errors When Opening PST Without Outlook
Older Outlook versions used ANSI PST while newer ones use Unicode PST. The 4n6 viewer reads both, but make sure the file is not zero bytes or corrupted before opening.
2. PST opens but shows empty folders
The PST header may be damaged. Run scanpst.exe on the file first, then reopen in the viewer.
3. Password protected PST will not open
Enter the password when prompted. If you do not have it, password recovery tools can extract or reset it before viewing.
4. Attachments will not preview inline
Some uncommon attachment types lack viewers on Windows. Save the attachment to disk and open it with the right application.
