Configure Calendar Repair Assistant Settings

  • Article

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

You can use the following Set-MailboxServer cmdlet parameters to configure CRA settings:

  • CalendarRepairIntervalEndWindow   Use this parameter to specify how far into the future you want CRA to look for calendar errors. The default value is 30 days.
  • CalendarRepairMissingItemFixDisabled   Use this parameter to disable CRA from fixing missing items. By default, CRA fixes missing calendar items on attendee's calendars. If an attendee is missing a calendar item, the item will be re-created.
  • CalendarRepairSchedule   Use this parameter to configure a schedule for when CRA will run. By default, a schedule for CRA isn't configured. If you don't specify a schedule, CRA won't run. If CRA doesn't finish processing the mailboxes on the server during the time that you've scheduled, it automatically resumes processing where it left off the next time it runs.
