One of my users kept complaining that they were getting reminders
about meetings that didn't exist. After checking is seams that
whenever he accepts an invite to a meeting Outlook sets it up as a
recurring meeting even when it's not.

Does he have a Dell and, if so, is the Outlookaddinsetup application listed
in Add/Remove Programs? Uninstall that application.
