Calendar and Resource Booking

This widget contains performance counters specific to the status of calendar and resource booking. The icons of the listed performance counters in the Statistic Name column change colors to reflect the listed counter's current state. Clicking any performance counter in the Statistic Name column takes you to the Performance Counter Details page for that performance counter.

If the value of a listed performance counter crosses the Warning threshold, the chart for the listed counter displays a yellow background.

Hovering over any time period within the chart displays detailed information about that time period in the tooltip. Hovering over a counter gives you detailed information about that performance counter.

Resource booking is an automated process of creating, changing, and deleting calendar requests for resource mailboxes. The Calendar and Resource Booking Attendant are the processes used by Exchange to fulfill requests for each. After a request is accepted, the free/busy data for the mailbox is updated.
