e mail support

[The Third]

I have e mail setup on my phone. Of course I have g mail too. The e mail is same address as I have on my Outlook on my computer. I realize that my phone will display my e mail I receive and it will still show up on my computer as well. The problem is that the mail I get on my phone deletes itself shortly after I have read it. Is there a way I can keep the mail on my phone until I delete it from the phone?
