I have an old Outlook ANSI PST file that has reached the 2GB size limit and is causing errors. I want to migrate it to the Unicode PST format using a free method. Is there any manual or Outlook solution that allows converting ANSI PST to Unicode PST safely without losing emails, contacts, or calendar items?
