We have a couple of iPhone users reported they were having calendar items disappear from their calendars. Many suggest to enable Calendar Repair Assistant for those users on mailbox servers. We are running Exchange 2010 SP2 RU7.  Do you know if there's any impact like performance when enabling Calendar Repair Assistant ? What's your best practice? Thanks in

Hi,

The Calendar Repair Assistant is used to detect and correct inconsistencies with single and recurring meeting items for mailboxes located on the Mailbox server. Then recipients won't miss meeting announcements or have unreliable meeting information. Based on my knowledge, there is no official article mentioning that enabling Calendar Repair Assistant has an impact on performance.

Hope my clarification can be helpful to you.

Best regards,
