ICloud calendar event won't delete

[mlbrowninsc]

I had my icloud account on my 950 for abit but have since deleted it. However Cortana continues to show the recuring work entry when I open the app. It is not listed in the calendar though. Always shows as a conflict with the same entry that is save in my outlook calendar. Is there a way to get rid of it? These little things drive me nuts. Thanks in advance for the help.
