I traded my Blackberry for an iPhone 5. I use my new iPhone 5 with MS Exchange. On my iPhone 5, when a colleague emails me a calendar invitation, my iPhone 5 makes the same tone as when there is calender reminder alert. I do not want any tone just because i receive a calendar invitation in my inbox, I do want the tone for the calender reminder alert. Also for some more background.. I have selected the option so I do not reveive any notification alert if I receive an email. What setting combination gets me to calendar invitation in my inbox = no notification on my iPhone and a tone ONLY for the calender reminder alert?
