Outlook 2003 Shared Calendar Meetings

I have shared my calendar to several work collegues, one of which is the team leader. My problem is that when the team leader sends out meeting requests I get emailed thier response, and not him. Is there any way to change it so that he gets the meeting responses instead of me?

We cannot allow his calendar to be shared, so it must be run on mine.

Thanks for your help,

James
