In a Microsoft Exchange Server 2007 Service Pack 1 (SP1) environment, an Exchange Server 2007 mailbox server randomly generates many transaction logs. Additionally, one of the following event errors is repeated in the Application event log for the same user:
Event ID : 8230 Raw Event ID : 8230 Category : General Source : EXCDO Type : Warning Message : An inconsistency was detected in <someone's address>: </calendar/xxx/xxx.EML>. The calendar is being repaired. If other errors occur with this calendar, please view the calendar using Microsoft Outlook Web Access. If a problem persists, please recreate the calendar or the containing mailbox.
Event ID : 8264 Raw Event ID : 8264 Category : General Source : EXCDO Type : Warning Message : The recurring appointment expansion in mailbox <someone's address> has taken too long. The free/busy information for this calendar may be inaccurate. This may be the result of many very old recurring appointments. To correct this, please remove them or change their start date to a more recent date.
To resolve this problem, install Update Rollup 1 for Exchange Server 2007 Service Pack 1. For more information about Update Rollup 1 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
