Outlook – unable to delete a particular calendar event in Outlook


I have a recurring meeting invite in my Outlook 2007 calendar. A few days ago the meeting organiser sent out a cancellation for this week's particular occurrence – normally it would be removed from my calendar but for some reason this didn't happen.

I am now trying to delete the occurrence manually which I can usually do either by double clicking and choosing to open that occurrence's invite, or by right clicking and choosing Delete, then choosing the occurrence. This way it won't impact the overall recurring invite.

However since the cancellation, right clicking the invite does nothing – no pop up appears. If I double click it, I receive the following error:

Cannot open this item. The operation failed. An object cannot be found.

I've tried changing the Current View from Day/Week/Month to some of the list views such as Events but I can't seem to find the meeting. It seems from the error that the actual message itself has long been deleted but for some reason it still persists in the calendar UI.

How can I remove it?

I couldn't resolve this within the Outlook desktop client - I tried a huge number of approaches but the event wouldn't budge.

The solution was to log on to my account using Outlook Web Access and delete the event from there. I have no idea what the root cause was, but this was the only working solution in the end!
