I use Outlook 2007 to manage email and to schedule appointments or meeting requests. Recently Outlook crashed and required a scan of the PST file before it would operate properly again. All seemed to be working without issue and then one of my recurring meetings continued to alert me that it was time for the meeting which was incorrect. After dismissing the item it would continue to warn of the issue which lead me to believe that the recurring meeting entry had become corrupted. After poking around some more I was able to verify that the meeting was in fact corrupted and read about all sorts of various steps that could be taken to resolve the issue. After attempting many of those steps including the /cleanreminders switch the meeting still existed and was still corrupted. Below I describe the error in more detail and a simple way to resolve a corrupted recurring meeting entry in the Outlook 2007 calendar.
