Recently I asked my colleague to send an email on Friday(4th October 2013). He failed to send me a mail on that day.
He simply changed the system date and time to Friday and sent me a mail on Monday yet it appears in my email client that it was sent on Friday. Is there any way to prove that he sent the mail on Monday?
I looked at his sent items but it shows Friday's date. I need to prove that he made the system date time to send me a mail on Monday. Both of us were using Windows 7 32 bit operating systems.
How to prove when the email was sent?
