Does anyone know why, when you delete a meeting from Outlook that the message box prompting you to send a cancellation to the attendees would not appear? I have tested this out sending a meeting request to someone on the same exchange server as myself and it does not make a difference if they accept the meeting, or provide no response. Normally as the meeting organizer, I would expect the message box to ask if I would like to send a cancellation or just delete the meeting but it allows me to delete the meeting anyway from my calendar without informing the attendees.
