I'm looking for a way to delete a calendar appointment for lots of users in our company. An assistant canceled an appointment that she sent to all users, but the cancelation didn't take for several users. Now several users have the appointment popping up (it's recurring) but the appointment isn't on the assistants calendar or the resource's calendar, so there's no way to try and resend the cancellation.
I have the details of the appointment, such as the name and dates. Is there any way to purge a meeting from all users' calendars from Exchange, or something like that?
