You have an Exchange Server 2010 organization. A user reports that some meetings are missing from her calendar.

You need to recover the missing calendar items. The solution must ensure that the missing calendar items are recovered automatically.

What should you do?

A.
Create and then configure a sharing policy.

B.
Set the schedule for the Managed Folder Assistant.

C.
Run the Set-MailboxCalendarConfiguration cmdlet.

D.
Set the schedule for the Calendar Repair Assistant (CRA).

Explanation:
This example sets the CRA to check all mailboxes on the server MBX02 every seven days and to process all calendars that require repairs every day in that seven day cycle.

Set-MailboxServer -Identity MBX02 -CalendarRepairWorkCycle 7.00:00:00 -CalendarRepairWorkCycleCheckpoint 1.00:00:00
