A system for providing feedback to a chairperson in an electronic meeting scheduling system to enable improved meeting resource management, in which a chairperson can indicate the attendance modes that are permitted for specific invitees to a meeting. The meeting invitations indicate to the invitees the attendance modes they are permitted to use. Meeting invitees are presented with user interface options allowing them to select from potentially multiple attendance modes, determined in response to inputs from the chairperson, and/or in response to information describing resources. As meeting resources are allocated to accepting invitees, those resources become unavailable for selection by subsequently accepting invitees. Meeting acceptances are collected such that indications of how accepting attendees will attend the meeting are made available in a chairperson interface so that the chairperson can adjust resources allocated for the meeting to reflect how accepting attendees are planning to attend.
