Responding to Meeting Invitations
If you have a Microsoft Exchange account set up on iPhone with Calendars enabled,
you can receive and respond to meeting invitations from people in your organization.
When you receive an invitation, the meeting appears in your calendar with a dotted
line around it. The
icon in the lower-right corner of the screen indicates the total
number of new invitations you have, as does the Calendar icon on the Home screen.
