Set Outlook 2010 (Exchange) to check email less often

I'd like to have Outlook check my email less often. I know about Send/Receive Groups, but as I understand it, if it's checking email through Exchange, that setting doesn't matter and email checking is instantaneous. To avoid workflow disruption, I'd like it to only show me new emails every 30 or 60 or whatever minutes. Is there a way to do that from the user's end (I am not an admin)? I can do it manually by clicking "work offline," but I'd like to have Outlook do this for me.

thanks, Ben
