ICS file as attachment to appointments+ confirmation email

Dear WPMUDEV team,
I was wondering if it is possible to attach the appointment as ICS file (iCal file format, RFC 5545) to the confirmation email of the service provider and/or the customer? It would be very helpful if the files included the date and time and the clients name at least. This would simplify the process for our service providers enormously, because the appointments could be directly imported into our exchange calendars.
Thank you!
