Outlook does not prompt the meeting organizer to send updates only to added or deleted attendees. How do I correct this?

After making meeting attendee updates to an Outlook meeting (adding or removing attendees), you should receive a prompt to send the following notifications:

• Send updates only to added or deleted attendees.
• Send updates to all attendees.
