A couple of my users are having a problem where they will accept a meeting request, but the accept notice sent to the meeting coordinator says, "Accepted on behalf of X user by Y user." I have triple checked the settings for the permissions, and none of the people accepting on behalf of have access. (Not that they are actually doing the accepting anyways.) We are currently using an Exchage2003 server with Office 2007. OS wise it's XP pro SP3.
