I just upgraded to a smart phone and have been using my gmail account to view emails on it. Most of the time if I view a new email on my phone and then later open outlook, they won't get downloaded or show up in outlook at all. Is there a setting that only downloads new and unread emails in outlook? I can't figure it out and I really need to be able to have outlook download everything on the gmail server and not just new emails. Thanks!

Even if I mark a read email as "unread" on my phone Outlook doesn't download it. So I'm stumped as to why Outlook pulls some in and not others. I didn't have this problem until I started receiving emails on my new phone.

Try using IMAP instead of POP (or pop instead of imap) on either your phone and/or outlook. Go into GMail settings and at the bottom are the directions on how to configure clients.
