We have about 3 iphones that are doing this which is weird. One went to her Calendar, updated the notes, resent it out to the attendees and after that the phone would keep sending it out every time you did something with the phone. Like it was stuck. It sent it out 20 times over 20 minutes seriously! Another phone did something similar. She would send a email out, and that person would receive that same email a few times again later. Has anyone noticed anything strange with this? They are both hooked up to Exchange Push. I had to remove Exchange from the first one to resolve that issue and re-add it. Rebooting the phones did not fix the problem either as it started right up as soon as it could.
