C:Windows.old > Users > username > AppData > Local > Microsoft > Outlook

  • Open the Outlook folder (old)
  • Locate the PST file and note the path
  • Launch Outlook
  • Click “File”

Due to this, Outlook contacts may go missing after the migration to Windows 10 and 11. To overcome this issue, try recreating the Outlook email profile on your Windows system.
