Any reason to not try the old "leave mail on server" setting in the email apps when you use pop?
There are three characteristics I'd like: 1) I want emails to be pushed to both Outlook and my iPhone 2) When I delete or read an email on one, I want it to delete or be marked as read on the other 3) I want the emails to reside on the devices, so that I can still read them without an Internet connection. With Exchange using offline file folders, these all work. With Gmail on Outlook and my iPhone, I can't get all three to work at the same time. If I use POP3, there's a race between my phone and Outlook and only whichever one retrieves the email first gets it. If I use IMAP, they can both get the email, but they don't store the emails when disconnected.
