Good question,
The spam email came in as an ordinary email in two instances. In one instance, it had the action buttons, 'Accept, Decline, Tentative'. The other instance had an attachment with an .ics file.

Initially, I thought the recipient (co-worker) had accendentally pressed the 'accept' action, but we ran a test and calendar event invitations are auto adding.

I would hope this would garner some attention. I would be willing to test this out with anybody. Additionally, I would like to understand this so I can explain it to management.
