Enable or Disable Calendar Repair for a Mailbox

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

The Calendar Repair Assistant (CRA) is a configurable, throttle-based Mailbox Assistant that runs within the Microsoft Exchange Mailbox Assistants service on Mailbox servers that run Microsoft Exchange Server 2010. CRA detects and corrects inconsistencies that occur for single and recurring calendar items for mailboxes that are homed on the Mailbox server that is running CRA. The purpose of this process is to make sure that recipients won't miss meetings or have unreliable meeting information.

By default, the CRA is not set to run automatically. To configure the CRA to run and repair calendar inconsistencies, use the set-mailboxserver cmdlet in the Exchange Management Shell to set the work cycle and work cycle checkpoint. The Exchange Management Console cannot be used to configure calendar repair log settings.

You can turn on or turn off calendar repair for a mailbox by using the Set-Mailbox cmdlet in the Shell.
