IMI Attendees Print is small utility specially designed for Microsoft
Outlook users to print the names of the people who have been invited to a
meeting and response status - Accepted, Declined, Tentative, None. From
Outlook, there no direct way to print the response status...

In Outlook, Meeting requests tracking tab should allow printing a list of
attendees' response, as well as sorting by status (accept, tentative,
decline) and name. This will help manage large meetings and provide an
attendance list to others.
