I will talk to him about it today and post it.
I don't understand the push/pull thing. I can tell you it uses imap not pop3 and when I read/delete an email on my phone, that email shows unread on my outlook.
He didn't do anything to my phone, I just went through the email set up and when it didn't work, he would change settings on the mail server till it worked.
So yeah. I will ask him and post it.
