Personal Folder File (*.pst)

Dear all,

Can you please guide me how to recover back the Personal Folder file (*.pst) that I had accidently deleted from my local HDD. Last 3 months important corporate e-mail messages had been lost. Is it anyway to recover it back? I
had tried using the System Recovery in Win XP Pro, but it’s fail to recover it back. Please help.

Thank you & have a great day,

Best regards,
Hendry
