What happens if he modifies the original Meeting instead - is an update
sent?
For it to modify an original it would need to be a Meeting (as opposed to an
Appt which has no invites) and for the original Meeting to be modified.

Hey, I have a problem I can’t figure out. We have a customer that is
having
problems with their outlook appointments. One guy says that when he sends
out an appointment to others it generates a new appointment on their end
instead of modifying the original appointment. Do you know if there’s
anything I can look at? I’ve looked through some of the setting and they
seem fine, but maybe I’m missing one that I don’t know about.
