Difference between cached Exchange and 'online with Exchange'

Hi All

I was hoping someone could explain the difference between cached and online with Exchange. We are using Exchange 2003 with Outlook 2007/2003 clients.

I thought that with online - Outlook has a constant MAPI (just one?) connection to Exchange. Whenever there is a new message in the user's mailbox, Exchange PUSHES this to Outlook.

With cached, Outlook PULLS messages at regular intervals (can these be defined)?

Hope someone can help.
