Programmatically rescheduling an instance of a recurring meeting that has users on different timezones and daylight savings time adjustments. That's pain that I will never forget.
For bonus points be that guy who had to implement such things on Lotus Domino.
Getting a bit tired with all the downvoting going on at the moment. I also have downvoting rights, but I hardly ever use them unless I see something offensive.
For example, at the moment it's, "why is Outlook ruining my life?"
