Select the online-manual scheduling mode to prevent unconfirmed appointments.
This mode permits students to propose appointments (according to your availability and capacity) and you to reject or accept proposed appointments. It will give you much more control over the student scheduling process.
You can view and/or edit your scheduling mode by completing the following steps:
1. Log into UNC Online (proctors.northcarolina.edu)
2. Click the "Settings" tab
