What if i wanted to convert vice-versa i.e Outlook Pst to Applemail?

Do you agree that some corrupted JPGs just can’t be fixed at all...a while back i had the "windows photo viewer can't open this picture because either photo viewer doesn't support this format” problem...i tried literally everything! But nothing would work

Just as a by the way. Anyone here who has used the Kernel for Windows Data Recovery? Would love to get a real hands on review of this.
