Disabling aoutcheck/sutosend in exchange 2003

I have set my individual send receive settings to where Outlook should
not check for e-mail more than every hour. However, my exchange
2003 server pushes e-mail in immediately. Is there somehting on the
exchange system manager that I can switch to change this?

Having e-mails pop up instantly does not let me or anyone else in the
office GTD.

Thanks,
