Tracking a Meeting
Attendees can choose Accept, Tentative, or Decline when
they reply to your meeting request. Once you start receiving replies,
Outlook automatically keeps track of the replies in the original request email
that was sent.
1.
Navigate to the Sent items folder, and find the original email you sent
requesting the meeting. Double-click to open the email in its own
window. You will not see the proper tabs if you view the email in the
preview pane.
2. Select
the Attendee Availability tab, as shown below, to see the results of
replies received. Note that you can add attendees in this window by typing
the name or using the Invite Others button. You can also re-check
the calendars of the attendees to see if they are available by choosing Show
attendee availability.

Canceling a
Meeting
The easiest way
to cancel a meeting you have created is to attempt to delete the meeting entry
from your own calendar. When you choose to delete the meeting, Outlook
recognizes that you were the meeting planner and asks if you would like to send
a cancellation notice to the attendees, as shown below.

When you choose to send a cancellation, Outlook brings up a cancellation
email addressed to the attendees and allows you to send the message from that
window. A cancellation message makes it easy for attendees to remove the
meeting from their calendar by providing a button for them to do so in the email
message window.
