I want to ask can we change the time when we send the e-mail through outlook express, for e.g if I send a e-mail to Mary at 17:00, but i want Mary receive my e-mail time is 19:00, can we do it?
Yes, you can do that
you just go to New Mail, and click option, there have an icon "don't send before "....and you can select which day and what time you send.
