hello. I had a problem similar to this with my iphone that i have had for 2 years but not i have a macbook pro and have run into it again.. I have a school email address (NYU). I have set up my school email to my email application on my macbook. I get my inbox mail fine but i can only see sent emails that I sent through the email app.. If I sent an email through the school's email system (on a computer at school, for example) I do not see this is my sent box of my mac email application. Likewise, I do not see the sent emails from my mac in the school's system. I set the outgoing server to what the school website said "smtp.nyu.edu" does anyone know what I can do to change this? thanks.
