Help Corporate Syn Inbox Help!

[Zummie]

I just got my X yesterday. I have one question. I added my school email to corporate sync. How can I have more than 5 emails show up on the inbox screen at a time. I can't find the option to add more. I have spent some hours trying to figure it out, both on the phone and google searching. I was able to do it on my Inc, but I am dumbfounded right now. I really don't want to spend 20 bucks on Touchdown. Thanks for the help.
