Remove events with Remove-CalendarEvents

Hi,

I have an ex-employee who scheduled several meetings before he left. I was able to run Remove-CalendarEvents w/o error. However, I am curious:

* Will the attendees receive cancellation emails in their inbox or this goes on behind the scene? I suppose it can silently remove the meetings from the attendees in the same Exchange environment.

* For external attendees, do they get cancellation emails? It seems to me they have to and it's up to the receiving end's mail system to process the cancellation. If that's the case, external attendees will get a bunch of cancellation emails.

Thank you.
