HelloToday I received this warning on our SBS 2008 server running Exchange 2007 SP1.An inconsistency was detected in useremailaddress: /Calendar/The system cannot find the file specified.AThe system cannot find the file specified.AFocusThe system cannot find the file specified.AThe system cannot find the file specified.A-170.EML. The calendar is being repaired. If a problem persists, please recreate the calendar or the containing mailbox. Is this something to be seriously worried about ? In addition, I noticed the relatively malformed warning. Is the "AFocus" a clue to the troublesome calendar entry ?Is there anything I can do to track down the problem calendar event (if there is one) ?Is there anything I should do to test/ensure the integrity of my exchange database ?Thank you for any help you can offer me.

Take a look at this article and see if it applies to you:Users are unable to receive meeting requests and meeting updates in Exchange Server 2007http://support.microsoft.com/kb/556074MCTS: Messaging | MCSE: S+M | Small Business Specialist

Hi JonThanks for your reply.I have not seen any:Status: RetryLast Error: 430 4.2.0STOREDRV.Deliver.Exception:MAPIExceptionCanNotCompletelogged in my event viewer so I don't think that link applies to my situation. But thanks all the same.

Hi,I suggest you use Outlook or OWA to open the mailbox of the user identified by event 8230, locate the calendar item and delete it. After that, please run we run Outlook /cleanfreebusy and press Enter. Then check this issue.ThanksAllen

AllenThank you for your reply.Is there anywhere that I can find any clues as to the offending calendar item please ?
