If you are experiencing an issue where events are being duplicated in your calendar (mainly ones that were imported via class schedule process), this document will guide you through steps to help resolve the problem.
Recently a case was open with Microsoft regarding a reoccurring issue where customers' events would be duplicated a numerous amount of times in their calendar, up to thousands. Microsoft believes it is another client causing the issue but the problem can not be easily reproduced in order to find a solution to the recreating events. As of now, there are currently two solutions we can provide to help resolve the problem.
